Cellular-resolution optogenetics reveals attenuation-by-suppression in visual cortical neurons

How neurons transform inputs into outputs is a fundamental building block of brain computation. Here, we measure neurons’ IO functions in the awake and intact brain, where ongoing network activity ...

The Hill function is the universal Hopfield barrier for sharpness of input–output responses

Biological systems can process information without expending energy, and the limit to what can be achieved in this way is known as a Hopfield barrier. We characterize this barrier for the sharpness of ...
