The neuronal representation of information in the human brain

However, the firing rates of neurons in different cortical areas are very different. In the inferior temporal visual cortex neurons with p ...

This is the all-or-none law, which had already been established for muscles and motor neurons: Incoming stimuli either produ ...

Protocadherin mediates collective axon extension of neurons
... Protocadherins are broadly classified as being either clustered or non-clustered. Past studies suggest that clustered protocadherins have some function in the self-repelling mechanism of dendrites to prevent binding between dendrites from the same neuron, while non-clustered protocadherins have been ...
