Hebbian synapses in visual cortex.
We discovered in slices of rat visual cortex that reliable long-term potentiation (LTP) of synaptic responses in layer III could be elicited by theta burst stimulation delivered to a site in the middle of the cortical thickness, corresponding mainly to layer IV. This synaptic plasticity was reflected in the extracellular field potentials and intracellular EPSPs in layer III, but was not observe...
متن کاملDo Hebbian synapses estimate entropy?
Hebbian learning is one of the mainstays of biologically inspired neural processing. Hebb’s rule is biologically plausible, and it has been extensively utilized in both computational neuroscience and in unsupervised training of neural systems. In these fields, Hebbian learning became synonymous for correlation learning. But it is known that correlation is a second order statistic of the data, s...
متن کاملHebbian synapses: biophysical mechanisms and algorithms.
We have examined the evolution of the concept of a Hebbian synaptic modification and have suggested a contemporary definition. The biophysical mechanism demonstrated in vitro to control the induction of one type of hippocampal LTP has been shown to satisfy our definition of a Hebbian synaptic modification. Whether this biophysical mechanism is involved in the organization of behavior in the man...

متن کاملSelf-organization of Hebbian Synapses in Hippocampal Neurons
We are exploring the significance of biological complexity for neuronal computation. Here we demonstrate that Hebbian synapses in realistically-modeled hippocampal pyramidal cells may give rise to two novel forms of self -organization in response to structured synaptic input. First, on the basis of the electrotonic relationships between synaptic contacts, a cell may become tuned to a small subs...
