Sensory Neuroscience: Linking Dopamine, Expectation, and Hallucinations [PDF]

Current Biology, 2018
Psychosis is associated with a dysregulation of the brain's dopamine-mediated neurotransmitter system. Yet, specific mechanisms underlying psychotic symptoms are not well understood. A new study has now uncovered a dopamine-dependent mechanism that explains why psychotic patients experience hallucinations.

Psychometrics of Disembodiment and Its Differential Modulation by Visuomotor and Visuotactile Mismatches

iScience, 2020
Summary: Altered states of embodiment are fundamental to the scientific understanding of bodily self consciousness. The feeling of disembodiment during everyday activities is common to clinical conditions; however, the direct study of disembodiment in ...

A connexin30 mutation rescues hearing and reveals roles for gap junctions in cochlear amplification and micromechanics

Nature Communications, 2017
A point mutation in the gap-junction protein connexin 30 stops early onset age-related hearing loss. Here, the authors show that gap junctions contribute to cochlear micromechanics and that cochlear amplification is likely controlled by extracellular ...

Sensory Neuroscience: Taste Responses in Primary Olfactory Cortex [PDF]

Current Biology, 2013
A new electrophysiological study in rodents demonstrates that taste-odor convergence occurs in posterior piriform olfactory cortex and calls for a reformulation of classic models of the central representation of flavor.

Emergence of functional sensory subtypes as defined by transient receptor potential channel expression

, 2007
The existence of heterogeneous populations of dorsal root ganglion (DRG) neurons conveying different somatosensory information is the basis for the perception of touch, temperature, and pain. A differential expression of transient receptor potential (TRP)

Representations of Sensory Signals and Abstract Categories in Brain Networks

, 2021
Many recent advances in artificial intelligence (AI) are rooted in visual neuroscience. However, ideas from more complicated paradigms like decision-making are less used.

Resting-state functional connectivity changes in the human brain from electrically-stimulated (2 Hz), rhythmic muscle contractions to the hand: An exploratory study

NeuroImage: Reports
Sensory nerves from contracting skeletal muscles can alter autonomic functions mediated by connections in the medulla and hypothalamus. We hypothesized that low-frequency, non-voluntary, rhythmical electrical stimulation of small muscles of the hand, in ...

Shedding light on human olfaction: Electrophysiological recordings from sensory neurons in acute slices of olfactory epithelium

iScience, 2023
Summary: The COVID-19 pandemic brought attention to our limited understanding of human olfactory physiology. While the cellular composition of the human olfactory epithelium is similar to that of other vertebrates, its functional properties are largely ...

Event-related brain potential correlates of human auditory sensory memory-trace formation

, 2005
The event-related potential (ERP) component mismatch negativity (MMN) is a neural marker of human echoic memory. MMN is elicited by deviant sounds embedded in a stream of frequent standards, reflecting the deviation from an inferred memory trace of the ...

A Network Analysis Approach to Detect and Differentiate Usher Syndrome Types Using miRNA Expression Profiles: A Pilot Study

BioMedInformatics
Background: Usher syndrome (USH) is a rare genetic disorder that affects both hearing and vision. It presents in three clinical types—USH1, USH2, and USH3—with varying onset, severity, and disease progression.
