Study reveals a potential link between respiration and neural activity changes in animal models.Spatial attention and running influence individual neurons independently with different dynamics.The neural circuitry that connects olfactory information about another mouse’s sex to decision-making in the brain determines the behavioral outcome as to whether aggression or affection is expressed.
A new study in rodents reveals a whisking oscillator that consists of a population of inhibitory neurons in the brainstem that fires in rhythmic bursts during whisking behaviors.Study reveals the molecular mechanism that allows neural networks to grow and branch out. A new study sheds light on why humans often use hand movements while talking. Researchers report rhythmic hand gestures affect rib cage movements, leading to a change in lung volume and ultimately aspects of the voice. Infants connect early vocal babbling with hand gestures, demonstrating an early connection between movement and vocal production.
Making Lab-Grown Brain Organoids ‘Brainier’
A new study offers guidelines and methods for consistently generating high-quality, well-structured brain organoids.Under anesthesia, neuron assemblies that respond to sound become indistinguishable from spontaneously active neurons. Findings suggest the state of unconsciousness produced by anesthesia forces the cerebral cortex to mask sensory input with spontaneous neural activity.Researchers have identified a population of neurons in the auditory cortex that responds to signing, but not any other type of music.A neural pathway that leads directly from the thalamus to the hypothalamus plays a critical role in processing touch information, a new study reveals.
Researchers reveal the role the prefrontal cortex plays in emotional processing and emotional suppression.Microglia cells listen to neighboring neurons and change their shape to match them.A newly developed artificial intelligence model can detect Parkinson’s disease by reading a person’s breathing patterns. The algorithm can also discern the severity of Parkinson’s disease and tract progression over time.Researchers have identified a network between the auditory cortex and thalamus that appears to blunt pain when an animal is exposed to specific sounds or noises.
Rhythmic bursts of activity in the prefrontal cortex reduce variability as an animal focuses on a task.Motor system neurons not only control movement, they also incite action.Researchers found that just as certain infectious diseases can cause cognitive problems in humans, infections can also hinder the cognition of animals too.Researchers identified a molecularly-defined cell population in the hypothalamus that causes a shift in the sleep-wake cycle as a result of exposure to psychostimulants.
. Super recognizers focus less on the eye region and distribute their gaze more evenly than typical viewers, extracting more information from other facial features.Overall, scientists and researchers are most innovative and creative early in their careers, a new study reports.Researchers have identified a new type of retinal ganglion cells.Sensory systems in the brain are closely interconnected, with regions that respond to touch also involved when we listen to specific sounds connected to touching certain objects.The Huntington’s disease protein huntingtin may have a role external to the neurodegenerative disease. Researchers say Huntingtin is involved in neural injury and regeneration.
Inserting a microelectrode deep into the brain to measure serotonin and dopamine levels of patients scheduled to receive deep brain stimulation is safe and effective.Fentanyl exposure produces specific EEG signatures in the brain. The findings also revealed the drug impairs people’s breathing four minutes before noticeable changes in alertness.Researchers explore how changes in the patterns of activity in the basolateral amygdala contribute to negative emotions such as fear, anxiety, and depression.Images of food stimulate a newly discovered population of food-responsive neurons in the ventral visual stream. Researchers believe there may be an evolutionary reason for this neural population that may reflect the significance of food in human culture.
In order to make autism research less harmful to the autism community, researchers propose new data-driven guidelines for discussing ASD in their work.War zone-related stress was associated with alterations in limbic gray matter microstructure, independent of a mental health or tbi diagnosis. In turn, these alterations were associated with cognitive function, including impaired response inhibition.Researchers have identified human-specific cell types in the prefrontal cortex. These unique cells may explain why humans are more susceptible to neuropsychiatric diseases than other primate species.Researchers have mapped four new areas of the human anterior prefrontal cortex that play critical roles in cognitive processing. Two of these newly mapped areas are larger in females than in males.Zooming out to image larger areas of the brain while using fMRI technology allows researchers to capture additional relevant information, offering a better understanding of neural interplay.People who experience chronic stress are more forgiving toward others than those who experience everyday stresses.
