It has been proposed that volumes of neural tissue may represent important processing elements. This viewpoint suggests one way that populations of synaptic elements cooperate to implement important computational capacities. I extend this v...

Cerebellum-like sensory structures in different groups of first have been shown to generate a negative image of predictable features of the sensory input. We show here that anti-Hebbian plasticity is present at the synapse between parallel ...

Redistribution of synaptic efficacy: a mechanism to generate infinite synaptic input diversity from a homogeneous population of neurons without changing absolute synaptic efficacies [0.03%]

Changing the reliability of neurotransmitter release results in a change in the efficacy of low frequency synaptic transmission and in the rate of high frequency synaptic depression thus it can not cause an uniform change in strength of syn...

Several forms of experience-dependent synaptic plasticity, long-term synaptic potentiation (LTP), and long-term depression (LTD) depend upon activation of NMDA receptors. Consideration of a theoretical synaptic 'learning rule' suggests how ...

Multielectrode recordings were performed in a variety of structures of structures of the mammalian brain in order to examine temporal relations among simultaneously measured neuronal responses. Data indicate close correlations between perce...

The role of feedback connections from area V2 to V1 was studied by reversible inactivation. When V2 was inactivated the responses of some V1 neurons to stimulation of the surround region were increased while responses to center stimulation ...

We examined the influence of stimulus context on the response of cells in primate V1 utilising both concentric and spatially discrete stimuli. The majority of cells (63/71) showed marked patch suppression, including non-oriented cells. This...

We have investigated several aspects of cortical organization in adult cats and in young kittens. First, we determined receptive field (RF) maps of correlated discharge between pairs of cortical cells. Unique bicellular RFs appear to convey...

In contrast with previous knowledge based on extracellular recordings, the recent development of intracellular techniques in vivo (sharp electrode or 'blind patch') ideally allows experimenters to analyze and dissect the contribution of fee...
