A neuron is the most granular unit in a neural network. Let's look at the second word of "neural network." A network is nothing but a set of vertices (also called nodes) whose edges are connected to each other. In the case of a neural network, neurons serve as the nodes. Let's ...
Behind the operation of a neuron sits a function. In the case of the linear neuron, we saw that its operations were based on a step function. We have a bunch of functions that are capable of capturing the nonlinearities. The sigmoid function is such a function, and the neurons that use...
Heat shock-mediated plasticity in the axon of a locust looming-sensitive visual interneuron. The model for these studies has been a visual interneuron, the descending contralateral movement detector (DCMD). This neuron relays information from visual... TGA Money - Queen's University (Canada). 被...
Neurotransmitters Neurotransmitters (NT) are endogenous chemicals that transmit signals from a neuron to a target cell across a synaptic cleft Synthesis of the NT can take place in the cell body, in the axon, or in the axon terminal. Storage of the NT in storage granules or vesicles in the ...
When I was "awakening" on the scene of neurobiology in the early thirties, the neuron concept was once again under heavy barrage from the "reticularists," then led by Jan Boeke at Utrecht and by Philipp Sthr, Jr., at Bonn. My first impressions about this nineteenth-century type of ...
