An action potential (AP) is a shift in the membrane voltage of a neuron generally caused by a sudden ion influx, resulting in excitation, allowing for the cell to send signals across its neural network. Spontaneous excitation can be crucial for organizing neural circuits, especially in sensory modalities. For hearing...
In the vertebrate retina, neurons process visual signals, generating feature selectivity in their activity levels. We use computational models to understand these behaviors by interpreting them mathematically. One component of this analysis is the spatial selectivity or receptive field, a property found in all visual sensory neurons. The neurons found...
To survive, animals, including human beings, have developed an amazing ability to learn the constantly changing environment. Specifically, detecting specific odorants in a noisy, variable background is crucial for finding food and water, mating, and avoiding potential dangers. For this purpose, rodents have developed an olfactory system that is powerful...
