An emerging wave of 'ambient' technologies has the potential to support learning in new and particular ways. In this paper we propose a 'trail model' of 'navigational learning' which links some particular learning needs to the potentialities of these technologies. In this context, we outline the design and use of an 'experience recorder', a technology to support learning in museums. In terms of policy for the e-society, these proposals are relevant to the need for personalised and individualised learning support.

28 male Long-Evans rats prepared with lesions of the middle cerebral artery displayed deficits in spatial navigational learning in a simple version of the Morris Water Maze task not seen in animals prepared with the same injury but administered 4 treatments with topiramate after surgery.

The role of route and survey information on the gradual acquisition of spatial knowledge was examined in a virtual environment (VE). Navigational focus was induced by having participants learn the environment using either an opaque (route) or transparent (survey) VE. Goal focus was induced by requiring participants to train to a sequential listing (route) or map-based (survey) criterion. During initial training, the presence of a route focus, based on the environment or the stated goal, led to better performance on a survey task than an exclusively survey focus. With increased training, performance with a survey-based focus matched that with a route-based focus. Early stage navigational learning in a survey-based environment benefited from the presence of a route goal. Later stage learning resulted in similar performance between route and survey goals and navigational learning environments.

AbstractFunctional plasticity of the brain decreases during ageing causing marked deficits in contextual learning, allocentric navigation and episodic memory. Adult neurogenesis is a prime example of hippocampal plasticity promoting the contextualisation of information and dramatically decreases during ageing. We found that a genetically-driven expansion of neural stem cells by overexpression of the cell cycle regulators Cdk4/cyclinD1 compensated the age-related decline in neurogenesis. This triggered an overall inhibitory effect on the trisynaptic hippocampal circuit resulting in a changed profile of CA1 sharp-wave ripples known to underlie memory consolidation. Most importantly, increased neurogenesis rescued the age-related switch from hippocampal to striatal learning strategies by rescuing allocentric navigation and contextual memory. Our study demonstrates that critical aspects of hippocampal function can be reversed in old age, or compensated throughout life, by exploiting the brain’s endogenous reserve of neural stem cells.
