Interoception refers to the process by which the nervous system senses and integrates signals originating from within the body, providing a momentary mapping of the body's internal landscape and its relationship to the outside world. Active inference is based on the premise that afferent sensory input to the brain is constantly shaped and modified by prior expectations. In this review we propose that interoceptive psychopathology results from two primary interoceptive dysfunctions: First, individuals have abnormally strong expectations of the situations that elicit bodily change (i.e., hyperprecise priors), and second, they have great difficulty adjusting these expectations when the environment changes (i.e., context rigidity). Here we discuss how these dysfunctions potentially manifest in mental illness and how interventions aimed at altering interoceptive processing can help the brain create a more realistic model of its internal state.

This paper is a survey of the neurological mechanisms involved in the regulation of immune function. Its specific focus is to explore the anatomical regions of the brain that mediate inflammatory responses throughout the body. It begins by briefly reviewing experiments that elucidate a connection between psychological process and immune function. It also introduces the physiological connections that enable communication between the central nervous system and peripheral immune system. It then examines the brain regions involved in regulating immune responses, with additional insights drawn from the principles of active inference in interoceptive processes. Keywords: Psychoneuroimmunology; Inflammation; Autonomic nervous system; conditioning; Insula; interoception; Active inference; Bayesian

1. The structure of the proboscides of the larva of Dibothriorhynchus grossum (Rud.) is described. Each proboscis is provided with four sets of extrinsic muscles, and there is an anterior dorso-ventral muscle mass connected to all four proboscides.2. The musculature of the body and scolex is described.3. The nervous system consists of a brain, two lateral nerve cords, two outer and inner anterior nerves on each side, twenty-five pairs of bothridial nerves to each bothridium, four longitudinal bothridial nerves connecting these latter before their entry into the bothridia, four proboscis nerves arising from the brain, and a series of lateral nerves supplying the lateral regions of the body.4. The so-called ganglia contain no nerve cells, these are present only in the posterior median commissure which is therefore the nerve centre.

The emulation theory of representation is developed and explored as a framework that can revealingly synthesize a wide variety of representational functions of the brain. The framework is based on constructs from control theory (forward models) and signal processing (Kalman filters). The idea is that in addition to simply engaging with the body and environment, the brain constructs neural circuits that act as models of the body and environment. During overt sensorimotor engagement, these models are driven by efference copies in parallel with the body and environment, in order to provide expectations of the sensory feedback, and to enhance and process sensory information. These models can also be run off-line in order to produce imagery, estimate outcomes of different actions, and evaluate and develop motor plans. The framework is initially developed within the context of motor control, where it has been shown that inner models running in parallel with the body can reduce the effects of feedback delay problems. The same mechanisms can account for motor imagery as the off-line driving of the emulator via efference copies. The framework is extended to account for visual imagery as the off-line driving of an emulator of the motor-visual loop. I also show how such systems can provide for amodal spatial imagery. Perception, including visual perception, results from such models being used to form expectations of, and to interpret, sensory input. I close by briefly outlining other cognitive functions that might also be synthesized within this framework, including reasoning, theory of mind phenomena, and language.

In the late 20th century, the discovery that the immune system and central nervous system were not autonomous revolutionized exploration of the mechanisms by which stress contributes to immune disorders and immune regulation contributes to mental illness. There is increasing evidence of stress as integrated across the brain and body. The immune system acts in concert with the peripheral nervous system to shape the brain’s perception of the environment. The brain in turn communicates with the endocrine and immune systems to guide their responses to that environment. Examining the groundwork of mechanisms governing communication between the body and brain will hopefully provide a better understanding of the ontogeny and symptomology of some mood disorders.

As you know, most mental illnesses are based on poisoning of the body, in particular the nervous system, poisonous substances or toxins that can come from the outside (exogenous diseases) or can form inside the body (autointoxication, endogenous diseases). If we could in some way stop the process of intoxication or at least reduce it, then we could achieve weakening or even cessation of exogenous or endogenous mental illness. If in exogenous intoxication psychoses the poison enters the body from the outside and may be more or less known to us (alcohol, drugs, etc.), then in endogenous psychoses (schizophrenia, epilepsy, etc.), the composition of toxins is unknown to us.

Our entire body, including the brain and nervous system, works with the help of various kinds of biological stuff which includes positively charged ions of elements like sodium, potassium, and calcium. The different body parts have different energy levels, and by measuring the energy level, we can also measure the fitness of an individual. Moreover, this energy and fitness are directly related to mental health and the signals being transmitted between the brain and other parts of the body. Various activities like walking, talking, eating, and thinking are performed with the help of these transmission signals. Another critical role played by them is that it helps in examining the mechanisms of cells present at various places in the human body and signaling the nervous system and brain if they are properly functioning or not. This manuscript is divided into two parts where, in the first part, it provides the introduction, background, and extensive literature survey on Kirlian experiments to measure the human's organ energy.

This chapter discusses the clinical necessity from which the intersection of neurology and psychiatry arose, exploring different eras and their associated intellectual milestones in order to understand the historical framework of contemporary neuropsychiatry. Identifying Hippocrates’ original acknowledgement of the relation of the human brain to epilepsy as a start point, the historical development of the field is traced. This encompasses Thomas Willis and his nascent descriptions of the limbic system, the philosophical and alchemical strides of the Enlightenment, and the motivations behind the Romantic era attempts to understand the brain. It then follows the growth of the field through the turn of the twentieth century, in spite of the prominence of psychoanalysis and the idea of the brainless mind, and finally the understanding of the ‘integrated action’ of the body and nervous system, which led to the integration of psychiatry and neurology, allowing for the first neuropsychiatric examinations of epilepsy.

Wagnerites and anti-Wagnerites frequently agreed at least in this: that the novelty of Wagner’s art was that it was directed first and foremost at the nerves. And it was not simply audience members who understood Wagner’s music dramas as essentially neural; it was also Wagner himself. Critics have long appreciated the importance of Wagner’s Beethoven essay of 1870, an essay that theorizes Wagner’s late movement toward “inner drama” and toward the dominance of music over text. Largely unappreciated, however, is the central importance of the neurological sciences in this transition; what Wagner aimed at in this essay was not simply the inner drama of the psyche but also—and inextricably—the inner drama of the body: that is, the drama of the brain and the nervous system. It is this profoundly neuropsychological understanding of art that drives Wagner’s late work—above all his final music drama, Parsifal.

The problems of the interdependence and unity of the brain and body have been put on a scientific basis by Pavlov and his successors. Bykov (1947) has, for example, been able to demonstrate that the cortex plays a leading part in the regulation of somatic processes, such as secretion of urine, blood pressure, peristalsis and metabolism. It is therefore reasonable to argue that lesions of the central nervous system will be reflected in the pathogenesis and course of morbid processes in the body. It does not follow, however, that this influence will necessarily be in the direction of greater lability, more rapid pathogenesis or more extensive destruction. The outstanding feature of the central nervous system is its plasticity and power of compensation. It is therefore possible and probable that those parts of the nervous system which remain intact will take over and compensate for the function of the lost ones. Emotion may, for example, lead to polyuria, but it does not follow that urinary secretion will be impaired in a leucotomized patient. The brain may well play an important part in the infective processes of a normal person, but the defence against infection in a microcephalic idiot may remain perfectly adequate, and may even be more effective than in a normal person, provided that the mechanism of the immunity and phagocytosis had been more fully mobilized in the course of his previous life.

Sleep restores energy to the body and provides relaxation particularly to the nervous system. It helps in building and restoring the control of the brain and nervous system over the muscles glands and other body systems. Nidra (Sleep) has its important role in healthy life.  The word Nidranasha denotes the phase of devoid of sleep which itself is the main Lakshana of this condition. Ayurveda indicates psychological respite as key along with Vataghna treatment in managing insomnia. Entire management is prescribed in the form of specific procedures, psychiatric treatment, drugs and Diet.
