Study: Thalamus is not a critical part of the brain pathway involved in maintaining consciousness

With a finding that will "rewrite neuroanatomy textbooks," University of Iowa neurologist Aaron Boes, MD, PhD, and his colleagues show that the thalamus is not a critical part of the brain pathway involved in keeping humans awake and conscious.

Scientists use hair-thin fiber endoscope to gain insights into hardly-accessible brain structures

It is the first time, scientists are able to achieve high-resolution observations of neuronal structures inside deep brain areas of living mice - by the use of the most minimally invasive endoscopic probe reported thus far.

Early-life stress in mice hinders neuron development, causing attention problems

Women are roughly twice as likely as men to develop depression, anxiety and other stress-related problems, including difficulty with attention, and new research from Brown University neuroscientists sheds light on the biological reasons why.

Discovery would help specify role of genetics in the development of neuropsychiatric disorders

Neurobiologists from I.M. Sechenov First Moscow State Medical University confirmed that stress in early age affects the mice with activated and deactivated CDH13 gene in different ways.

Scientists uncover neural code that predicts behavior

Scientists at the National Eye Institute have found that neurons in the superior colliculus, an ancient midbrain structure found in all vertebrates, are key players in allowing us to detect visual objects and events.

Human brain may stay active for hours after death

One question that has baffled mankind is “after-death experience” or the experience after the heart stops beating.

Brain-computer interface enables people with tetraplegia to operate tablet devices

An investigational brain-computer interface can enable people with paralysis to directly operate an off-the-shelf tablet device by thinking about making cursor movements and clicks, according to a study published November 21, 2018 in the open-access journal PLOS ONE by Paul Nuyujukian, Jose Albites-Sanabria, and Jad Saab from the BrainGate consortium, USA, and colleagues.

Thickness of the brain's outer layer influences how neurons process information

Researchers at the University of Queensland have discovered that the thickness of the brain's outer layer influences how individual neurons process information.

Brain imaging study reveals 'hot spot' for cue-reactivity in substance users

When patients with dependence on alcohol, cocaine or nicotine are shown drug cues, or images related to the substance, an area of their brain known as the medial prefrontal cortex shows increased activity, report investigators at the Medical University of South Carolina in an article published online September 7, 2018 in Translational Psychiatry.

MDMA could help gain trust but does not make one naive find researchers

MDMA or ecstasy pills can help individuals trust more and cooperate say a team of researchers who are looking at its properties that could help treat psychological disorders. The study was published this week in the latest issue of the Journal of Neuroscience.

Study explores how the moving brain processes visual information

What we see is not only determined by what is really there, but also depends on whether we are paying attention, whether we are moving, excited or interested.

First probabilistic atlas of thalamus nuclei to better understand the brain

A multidisciplinary study led by BCBL, a Basque research center, opens the door to the investigation of the structure and functions of human thalamic nuclei and their involvement in Alzheimer's, dyslexia, epilepsy, Huntington's and schizophrenia.

Study: Personality, mental health affect how people value personal control in decision making

Personality traits and mental health affect how people value personal control in decision making, according to a new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

Scientists identify novel target for neuron regeneration, functional recovery in spinal cord injury

Restoring the ability to walk following spinal cord injury requires neurons in the brain to reestablish communication pathways with neurons in the spinal cord.

Researchers pinpoint brain region responsible for 'on-the-fly' decision-making

Researchers have pinpointed a part of the human brain responsible for “on-the-fly” decision-making. According to the findings published in JNeurosci, the anterior cingulate cortex integrates disparate information about the desirability and amount of an option to inform choice.

Researchers find first direct evidence that cerebellum plays role in cognitive functions

It is known that certain areas of the brain are responsible for certain functions of the body. The cerebellum, a structure found in the back of the skull, is known to be important for the control of movement, while the frontal cortex is responsible for cognitive functions such as short-term memory and decision making.

CityU develops first microarrayed 3D neuronal culture platform

Neuronal development is often regulated by the graded distribution of guidance molecules, which can either attract or repel the neuronal migration or neurite projection when presented in a format of concentration gradients, or chemotaxis. However, many details about the process is largely unexplored.

Research highlights physical changes in the brain of self-injuring teen girls

The brains of teenage girls who engage in serious forms of self-harm, including cutting, show features similar to those seen in adults with borderline personality disorder, a severe and hard-to-treat mental illness, a new study has found.

Transgenic rat model may provide new insights into cerebral amyloid angiopathy

In a report in The American Journal of Pathology investigators describe the generation of a successful novel transgenic rat model that accumulates amyloid specifically in brain blood vessels and strongly mimics many of the associated detrimental changes that are observed in humans - a condition known as cerebral amyloid angiopathy, which is also commonly observed in Alzheimer disease.

Neuroscientists receive $16.75 million from BRAIN Initiative to decipher the brain's visual system

The BRAIN Initiative has awarded $16.75 million to a team of neuroscientists charged with deciphering the primary visual cortex, a few hundred million brain cells that play a key role in making sense of what the eye sees.
