Neural inhibition for continual learning and memory.
Curr Opin Neurobiol, 2021 Humans are able to continually learn new information and acquire skills that meet the demands of an ever-changing environment. Yet, this new learning does not necessarily occur at the expense of old memories. The specialised biological mechanisms that permit continual learning in humans and other mammals are not fully understood.

The neural system for the inhibition of startle [PDF]
Bulletin of the Psychonomic Society, 1979 In the rat, lesion of the lateral tegmentum but not of the raphee eliminated inhibition of acoustic startle by prior acoustic and visual stimuli with lead times of 50 msec. Since lesion of the lateral tegmentum did not interfere with latency reduction (when the same prior stimuli had lead times of 4 msec), it is concluded that lesion of the lateral ...

Neural noise and cortical inhibition in schizophrenia [PDF]
Brain Stimulation, 2020 Neural information processing is subject to noise and this leads to variability in neural firing and behavior. Schizophrenia has been associated with both more variable motor control and impaired cortical inhibition, which is crucial for excitatory/inhibitory balance in neural commands.In this study, we hypothesized that impaired intracortical ...

Cumulative inhibition in neural networks [PDF]
Cognitive Processing, 2018 We show how a multi-resolution network can model the development of acuity and coarse-to-fine processing in the mammalian visual cortex. The network adapts to input statistics in an unsupervised manner, and learns a coarse-to-fine representation by using cumulative inhibition of nodes within a network layer.

Neural Correlates of Attentional Modulation of Prepulse Inhibition [PDF]
Frontiers in Human Neuroscience, 2021 Prepulse inhibition (PPI) refers to the suppression of the startle reflex when the intense startling stimulus is shortly (20–500 ms) preceded by a weak non-startling stimulus (prepulse). Although the main neural correlates of PPI lie in the brainstem, previous research has revealed that PPI can be top-down modulated by attention.

Behavioral and neural mechanisms of latent inhibition
Learning & Memory, 2022 Fear is an adaptive emotion that serves to protect an organism against potential dangers. It is often studied using classical conditioning paradigms where a conditioned stimulus is paired with an aversive unconditioned stimulus to induce a threat response.

Dynamic neural field with local inhibition [PDF]
Biological Cybernetics, 2005 A lateral-inhibition type neural field model with restricted connections is presented here and represents an experimental extension of the continuum neural field theory (CNFT) by suppression of the global inhibition. A modified CNFT equation is introduced and allows for a locally defined inhibition to spatially expand within the network and results in ...

Neural and Neurochemical Mechanisms of Pain Inhibition [PDF]
Anaesthesia and Intensive Care, 1982 Recent studies which suggest the existence of an endogenous neural substrate of pain inhibition are reviewed. Electrical stimulation of some areas of the medial brain stem in laboratory rats has produced a dramatic degree of analgesia. Such stimulation-produced analgesia is partially blocked by an opiate antagonist drug.

Anti-Neural-Inhibition: A Conserved Mechanism for Neural Induction [PDF]
Cell, 1997 While the previous discussion highlights the striking degree of evolutionary conservation in the mechanism for partitioning the ectoderm into neural versus nonneural components, it is not as clear that other aspects of D/V patterning have been conserved.

Dendritic Inhibition Enhances Neural Coding Properties [PDF]
Cerebral Cortex, 2001 The presence of a large number of inhibitory contacts at the soma and axon initial segment of cortical pyramidal cells has inspired a large and influential class of neural network model that use post-integration lateral inhibition as a mechanism for competition between nodes.
