Receptive Fields and Neural Analysis
Flashcards do conjunto (6)
- 1Receptive fieldArea of sensory surface which, if stimulated, will affect a neuron’s state (membrane potential, threshold, or firing rate)
Receptive field area inversely proportional to acuity - 2Sustained vs transientTemporal – the response can vary in relation to time.
Sustained – if you turn the stimulus on, the firing rate of the neuron will remain.
A sustained response will tell you if something is on. A transient response will tell you if something has come on. - 3Linear vs non-linear responsesLinear – the response is simply the sum of the excitation and inhibition of the receptive field
Non-linear – the response is not simply the sum of excitation and inhibition in the receptive field; often, there are no distinctive on- or off- regions - 4Simple cellsOrientation tuned
Linear - 5Complex cellsOrientation tuned
Directionally selective
Non-linear - 6Receptive field area tend to increase throughout successive levels of processing hierarchy in the brainSuggests pooling of information
