Topic: excitatory input

A central principle of most sensory cortices is that they are topographically organized- neurons close to each other have similar tuning properties, varying along a physical stimulus feature. Such an organization has not been found yet in the olfactory system. This is because odors constitute discrete objects that do not vary along a specific physical dimension. Here, we have developed a method to reveal the receptive field (RF) of anterior piriform cortex (aPC) neurons. The RF is defined as the glomeruli set that affects the recorded aPC neuron. We found that, on average, an aPC neuron RF com
