Optical manipulation of neural activity
WebDec 22, 2014 · We have developed an all-optical strategy for activating and recording the same neurons with cellular resolution in mice in vivo using a dual two-photon optogenetic and calcium imaging approach. The strategy relies on viral coexpression of a genetically encoded activity sensor (GCaMP6s) and a red-shifted opsin (C1V1). WebLinear neural network. The simplest kind of feedforward neural network is a linear network, which consists of a single layer of output nodes; the inputs are fed directly to the outputs via a series of weights. The sum of the products of the weights and the inputs is calculated in each node. The mean squared errors between these calculated outputs and a given target …
