The role of contrast adaptation in saccadic suppression in humans. [PDF]

PLoS ONE, 2014
The idea of retinal and ex-retinal sources of saccadic suppression has long been established in previous studies. However, how they are implemented in local circuit remains unknown.

Dynamics of cortical contrast adaptation predict perception of signals in noise

Nature Communications, 2023
Neurons throughout the sensory pathway adapt their responses depending on the statistical structure of the sensory environment. Contrast gain control is a form of adaptation in the auditory cortex, but it is unclear whether the dynamics of gain control ...

Cognitive adaptation of sonar gain control in the bottlenose dolphin. [PDF]

PLoS ONE, 2014
Echolocating animals adjust the transmit intensity and receive sensitivity of their sonar in order to regulate the sensation level of their echoes; this process is often termed automatic gain control. Gain control is considered not to be under the animal'

A computational mechanism for unified gain and timing control in the cerebellum. [PDF]

PLoS ONE, 2012
Precise gain and timing control is the goal of cerebellar motor learning. Because the basic neural circuitry of the cerebellum is homogeneous throughout the cerebellar cortex, a single computational mechanism may be used for simultaneous gain and timing ...
