Cholinergic modulation of spatial learning, memory and navigation

The current state of the art of the division of labour within this complex ‘navigation system’ is reviewed, with special focus on how subcortical cholinergic inputs may regulate various aspects of spatial learning, memory and navigation.

Complementary Roles of the Hippocampus and the Dorsomedial Striatum during Spatial and Sequence-Based Navigation Behavior

The data support the view that the hippocampus organizes information into a spatio-temporal representation, which can then be used by the DMS to perform goal-directed navigation.

Conjunctive encoding of movement and reward by ventral tegmental area neurons in the freely navigating rodent.

VTA neural activity was recorded as rats performed a spatial memory task under varying contextual conditions, suggesting that movement- and reward-related firing are two independently regulated modes of VTA neuronal activity and may serve separate functions.

Self Regulation of Memory Processing Centers of the Brain

Current challenges are to understand what makes each brain area so unique that they mediate different types of memory, and to determine how the different brain areas that process mnemonic information work together in a continuous and seemingly automatic way.

Ventral tegmental area and substantia nigra neural correlates of spatial learning.

VTA and SNc neural activity as navigating rats engaged in new spatial learning and experienced changes in expected goal locations imply that VTA andSNc play complementary yet distinct roles in spatial learning to optimize adaptive behavior.

Learning processing in the basal ganglia: A mosaic of broken mirrors




A neural systems analysis of adaptive navigation

A model of complex learning (rodent adaptive navigation) that could be used to study dynamically interactive neural systems and evidence consistent with the view that during navigation is presented that the limbic thalamus and limbic cortex is primarily responsible for the integration of current and expected sensory information.

Parallel processing across neural systems: Implications for a multiple memory system hypothesis

Memory influences on hippocampal and striatal neural codes: Effects of a shift between task rules

Context-dependent reorganization of spatial and movement representations by simultaneously recorded hippocampal and striatal neurons during performance of allocentric and egocentric tasks.

The striking overall similarity between hippocampal and striatal neural responses to context manipulation (regardless of strategy) suggests that these structures operate continuously, and in parallel, during multiple forms of learning.

Learning-related coordination of striatal and hippocampal theta rhythms during acquisition of a procedural maze task

It is suggested that rhythmic oscillations, including theta-band activity, could influence not only neural processing in cortico-basal ganglia circuits but also dynamic interactions between basal ganglia-based and hippocampus-based forebrain circuits during the acquisition and performance of learned behaviors.

Learning and memory functions of the Basal Ganglia.

Evidence suggests that during learning, basal ganglia and medial temporal lobe memory systems are activated simultaneously and that in some learning situations competitive interference exists between these two systems.

Hippocampal place cells, context, and episodic memory

Recent data from the laboratory, together with previous findings, indicate that hippocampal place fields and neuronal responses to task‐relevant stimuli are highly sensitive to the context, even when the contexts are defined by abstract task demands rather than the spatial geometry of the environment.

Hippocampal and neocortical interactions during context discrimination: Electrophysiological evidence from the rat

Evidence that a primary consequence of hippocampal processing is the discrimination of meaningful contexts is described, and the functional significance of neocortical circuits that likely receive hippocampal output messages are described in terms of their contribution to the control of ongoing behavioral and cognitive strategy, especially during active navigation.
