Sensory uncertainty decoded from visual cortex predicts behavior.

Summary of "Sensory uncertainty decoded from visual cortex predicts behavior."

Bayesian theories of neural coding propose that sensory uncertainty is represented by a probability distribution encoded in neural population activity, but direct neural evidence supporting this hypothesis is currently lacking. Using fMRI in combination with a generative model-based analysis, we found that probability distributions reflecting sensory uncertainty could reliably be estimated from human visual cortex and, moreover, that observers appeared to use knowledge of this uncertainty in their perceptual decisions.

Visual Experience Regulates the Intrinsic Excitability of Visual Cortical Neurons to Maintain Sensory Function.

This in vivo study shows that both intrinsic and sensory-evoked synaptic properties of layer 2/3 neurons in mouse visual cortex are modified by ongoing visual input. Following visual deprivation, int...

Selective Modulation of Early Visual Cortical Activity by Movement Intention.

The primate visual system contains myriad feedback projections from higher- to lower-order cortical areas, an architecture that has been implicated in the top-down modulation of early visual areas dur...

Comparing Bayesian and non-Bayesian accounts of human confidence reports.

Humans can meaningfully report their confidence in a perceptual or cognitive decision. It is widely believed that these reports reflect the Bayesian probability that the decision is correct, but this ...

The Spatial Structure of Neural Encoding in Mouse Posterior Cortex during Navigation.

Navigation engages many cortical areas, including visual, parietal, and retrosplenial cortices. These regions have been mapped anatomically and with sensory stimuli and studied individually during beh...

Sensory manipulation results in increased dorsolateral prefrontal cortex activation during static postural balance in sedentary older adults: An fNIRS study.

The dorsolateral prefrontal cortex (DLPFC) is involved with allocating attentional resources to maintain postural control. However, it is unknown whether age-related structural and functional declines...

Role of the Posterior Parietal Cortex in the Processing of Sensory Information

Although the primary motor cortex is considered has the common final pathway of motor commands, it is influenced by several structures as, for example, the premotor cortex and the posterio...

Sensori-motor and Perceptual Functions of the PPC.

To produce hand's movement directed towards a target, the investigator must combine several sensory information, such as vision or proprioception. The posterior parietal cortex (PPC) is a ...

Effects of the Visual Stimulation on the Motor and Visual Cortex in Migraneurs With and Without Aura

The aim of this study is to investigate the motor and visual cortex excitability in response to visual stimulation of migraineurs with and without aura compared to healthy individuals. For...

The Effects of TMS on Memory-Consolidation in Human Primary Visual Cortex

Rapid Transcranial Magnetic Stimulation will be used in order to examine whether the human primary visual cortex is essential to visual memory consolidation.

The purpose of this study is to determine if and to what extend a composite measure of treatment motivation and behavior change motivation predicts alcohol treatment success. It is expecte...

Medical and Biotech [MESH] Definitions

A composite area of the cerebral cortex concerned with motor control and sensory perception comprising the motor cortex areas, the somatosensory areas, the gustatory cortex, the olfactory areas, the auditory cortex, and the visual cortex.

A term used in Eastern European research literature on brain and behavior physiology for cortical functions. It refers to the highest level of integrative function of the brain, centered in the CEREBRAL CORTEX, regulating language, thought, and behavior via sensory, motor, and cognitive processes.

Repetitive visual hallucinations experienced mostly by elderly with diminished visual acuity or visual field loss, with awareness of the fictional nature of their hallucinations. It is not associated with delusions and other sensory hallucinations.

The electric response evoked in the cerebral cortex by visual stimulation or stimulation of the visual pathways.

A nonspecific term referring to impaired vision. Major subcategories include stimulus deprivation-induced amblyopia and toxic amblyopia. Stimulus deprivation-induced amblyopia is a developmental disorder of the visual cortex. A discrepancy between visual information received by the visual cortex from each eye results in abnormal cortical development. STRABISMUS and REFRACTIVE ERRORS may cause this condition. Toxic amblyopia is a disorder of the OPTIC NERVE which is associated with ALCOHOLISM, tobacco SMOKING, and other toxins and as an adverse effect of the use of some medications.
