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 ...

Adaptive Allocation of Attentional Gain [PDF]
The Journal of Neuroscience, 2009 Humans are adept at distinguishing between stimuli that are very similar, an ability that is particularly crucial when the outcome is of serious consequence (e.g., for a surgeon or air-traffic controller). Traditionally, selective attention was thought to facilitate perception by increasing the gain of sensory neurons tuned to the defining features of ...

Obligatory Adaptation of Saccade Gains [PDF]
Journal of Neurophysiology, 2008 We tested the hypothesis that saccade gains adapt to minimize error between the visual target and the saccade endpoint of every saccade we make even when the errors on sequential saccades are not directionally consistent. We utilized a state-space model that estimated the degree to which saccade gains were modified by the magnitude and direction of ...

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'

On gain adaptation in adaptive control [PDF]
IEEE Transactions on Automatic Control, 2003 The adaptive high-gain output feedback strategy u(t)=-k(t)y(t), (d/dt)k(t)=/spl par/y(t)/spl par//sup 2/ is well established in the context of linear, minimum-phase, m-input m-output systems (A, B, C) with the property that spec(CB)/spl sub//spl Copf//sub +/; the strategy applied to any such linear system achieves the performance objectives of: 1 ...

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 ...

Robust observer design under measurement noise with gain adaptation and saturated estimates [PDF]
, 2017 We use incremental homogeneity, gain adaptation and incremental observability for proving new results on robust observer design for systems with noisy measurement and bounded trajectories.
