1. Addition of a homogenate of corpora cardiaca to the fluid bathing an isolated hind gut of Periplaneta produces an increase in tonus, amplitude, frequency and co-ordination of contractions. 2. The corpus cardiacum acts by stimulating cells in the upper colon to release an indolalkylamine. 3. This amine acts on the mucles through a peripheral nervous system which can function in isolation from the central nervous system.

Thiopentone and pentobarbitone reduce the time constant of decay of miniature end-plate currents when applied in anaesthetic concentrations to the neuromuscular junction. Such an effect at central synapses would lead to failure of synaptic transmission in the central nervous system and may reflect a common mode of action of many anaesthetic drugs.

Normal saline (0.9% NaCl, pH 5.85) infused intracisternally in dogs has a general excitatory effect on the central nervous system, producing increased rate and depth of respiration and increased muscular tone with muscle discharges, especially from facial, cranial, and neck muscles. This excitatory effect correlated most closely with changes in systemic pCO2. being enhanced when the arterial pCO2 was decreased and being depressed when the arterial pCO2 was increased. This excitatory effect also can be depressed or abolished by relatively small concentrations of CaCl2. Mode of action is discussed.

Wilhelm Siegmund Feldberg, one of the greatest neuropharmacologists of the 20th century, was born in Hamburg on 19 November 1900. During a working life of 65 years, he published over 350 papers. His early work in Berlin on the pharmacology of histamine and acetylcholine was followed in the 1930s by his fundamental work with Dale, which finally established the chemical nature of synaptic transmission in the peripheral nervous system. In later years he turned to the central nervous system, introducing a new and widely adopted experimental approach to elucidate the site and mode of action of drugs in the brain.

For some years, we have been engaged in an investigation into the mode of action of toxins upon the central nervous system, and up to the present time have devoted our attention exclusively to the question of the upward passage of bacterial poisons along the sheaths of peripheral nerves to the spinal cord and brain. Experiment has shown us that toxins readily travel upwards in the perineural lymphatics, in which they induce an inflammation whose phenomena vary with the intensity of the irritant; and that this is continued without interruption to the central nervous system, granted that the toxins gain that level. Continuity of extension is, therefore, an important feature of lymphogenous inflammation, and is as constant in the central as in the peripheral nervous system.
