Behavioural Context and a Distributed System: Metabolic Mapping Studies of the Basal Ganglia
Abstract Behavioural context is known to affect neural activity in the striatum. Responses of single cells increase to rewarding stimuli, or drop out as a bar press or saccade is learned. Networks that can accomplish a unique response to changing contexts...
Cortical Populations and Behaviour: Hebb's Thread
Abstract This paper discusses work on the function of the motor cortex as revealed by single cell recordings in monkeys and artificial neural network modelling. Our key conceptual approach both in behavioural neuroscience and neural network modeling...
Neuromodulation, Development and Synaptic Plasticity
Abstract We discuss parallels in the mechanisms underlying use-dependent synaptic plasticity during development and long-term potentiation (LTP) and long-term depression (LTD) in neocortical synapses. Neuromodulators, such as norepinephrine, serotonin,...
Ontogenetic Constraints on Neural and Behavioral Plasticity: Evidence from Imprinting and Face Processing
Abstract This paper addresses the extent and limits on brain plasticity during development through the detailed study of imprinting in the domestic chick and the development of face processing in human infants. In both of these systems evidence for constraints...
Synaptic Plasticity and the Organization of Behaviour after Early and Late Brain Injury
Abstract Hebb proposed that synaptic change underlies behavioural and cognitive plasticity. When applied to recovery from brain injury, the general hypothesis is that if there is recovery following brain injury, then there ought to be a correlated synaptic...
The Deterioration of Semantic Memory in Alzheimer's Disease
Abstract Semantic memory impairment is a common feature of dementia of the Alzheimer type (DAT). Recent research has shown that patients with DAT are more impaired (relative to non-demented controls) in generating exemplars from a particular semantic...
The First Panic Attack: A Neurobiological Theory
Abstract We extend a neurodevelopmental model of specific phobias to the etiology of an initial panic attack and its elaboration into panic disorder. An important difference between the initial panic attack and specific phobia is the developmental timing...
The Hebb Legacy
Donald Olding Hebb (1904-1985) was, during his lifetime, an extraordinarily influential figure for the discipline of psychology. His principled opposition to radical behaviourism and emphasis on understanding what goes on between stimulus and response...
The Organization of Behaviour Revisited
Abstract Donald Hebb pioneered many current themes in behavioural neuroscience. He saw psychology as a biological science, but one in which the organization of behaviour must remain the central concern. Through penetrating theoretical concepts, including...
Webs, Cell Assemblies, and Chunking in Neural Nets: Introduction
Abstract This introduction to Wickelgren (1992), describes a theory of idea representation and learning in the cerebral cortex and seven properties of Hebb's (1949) formulation of cell assemblies that have played a major role in all such neural net models....
