Dopamine: Far More Than Just the 'Happy Hormone'

Aug. 31, 2016 — Dopamine is a so-called messenger substance or neurotransmitter that conveys signals between neurons. It not only controls mental and emotional responses but also motor reactions. Dopamine is ... read more

Aug. 30, 2016 — A research team has identified the pain transmission mechanism at the molecular level and presented new solutions for the understanding of pain signals and the development of pain ... read more

How PSD Forms and Why Defects Can Cause Autism

Aug. 25, 2016 — Scientists have discovered that SynGAP and PSD-95, two abundance proteins in PSD that are known to cause autism when mutated, can form an autonomously assembled network structure both in test-tube ... read more

Aug. 25, 2016 — A major therapeutic challenge, the retinal prostheses that have been under development during the past ten years can enable some blind subjects to perceive light signals, but the image thus restored ... read more

Aug. 25, 2016 — Scientists are testing a drug that could boost levels of critical protective protein in brain. In the study, the team conducted tests in a mouse model of Alzheimer's disease by raising the ... read more

Aug. 25, 2016 — Researchers have revealed that microglia -- cells involved in immune functions in the brain -- also influence brain connectivity and formation of new links between neurons in the developing brain. By ... read more

Aug. 24, 2016 — A new study found that adult rats with disruptions in their social hierarchy produced far fewer new neurons, and reacted to the surrounding upheaval by favoring the company of familiar rats. The ... read more

Concussions and Brain Injury: Can Omega-3 Intake Aid in Brain Health Recovery?

Aug. 24, 2016 — The treatment of concussions and traumatic brain injury (TBI) is a clinical challenge. Clinical studies thus far have failed to identify an effective treatment strategy when a combination of targets ... read more

Scientists Identify Spark Plug That Ignites Nerve Cell Demise in ALS

Aug. 24, 2016 — Scientists have pinpointed an enzyme that triggers rapid demise of nerve cells in people with ALS. The research team describes a molecular chain of events that culminates in the stripping of the ... read more

A Brain Circuit to Push Past Nutritional Stress

Aug. 24, 2016 — Nutritional stress is a normal part of life; going hungry on a short-term basis generally does not impair important functions. The brain coordinates the response to nutritional stress but how it does ... read more

In Some Genetic Cases of Microcephaly, Stem Cells Fail to Launch

Aug. 24, 2016 — In a very severe, genetic form of microcephaly, stem cells in the brain fail to divide, according to a new study that may provide important clues to understanding how the Zika virus affects the ... read more

Mechanism That Alters Neural Excitability Offers Window Into Neuropsychiatric Disease

Aug. 23, 2016 — Researchers show, for the first time, that the well-known mechanism of gene expression control -- dynamic changes in DNA methylation -- is also involved in changes to the excitability of neural ... read more

Relief for Epilepsy at the Scale of a Single Cell

Aug. 23, 2016 — Researchers have developed in collaboration with French colleagues a small device that both detects the initial signal of an epileptic attack and doses a substance that effectively stops it. All this ... read more

Too Much Activity in Certain Areas of the Brain Is Bad for Memory and Attention

Aug. 23, 2016 — Researchers have found that faulty inhibitory neurotransmission and abnormally increased activity in the hippocampus impairs our memory and ... read more

Aug. 23, 2016 — Researchers from the epicenter of the current Zika virus outbreak have released a report on imaging findings in babies and fetuses infected with the Zika virus. Zika virus is most dangerous when ... read more

Bioimaging: A Clear View of the Nervous System

Aug. 22, 2016 — A new and versatile imaging technique enables researchers to trace the trajectories of whole nerve cells and provides extensive insights into the structure of neuronal ... read more

Aug. 22, 2016 — Scientists have demonstrated the role of lysosomal vesicles in transporting alpha-synuclein aggregates, responsible for Parkinson's and other neurodegenerative diseases, between neurons. These ... read more

Aug. 22, 2016 — In a classic experiment, Ivan Pavlov conditioned dogs to salivate at the ringing of a bell. Now, scientists can see what happens in the brains of live animals during this experiment with a new ... read more

Aug. 19, 2016 — A fundamental question in neuroscience is how neuronal circuits give rise to brain function, as disruptions in these connections can lead to brain disorders. Translating the rules governing the ... read more

Electrical Synapses in the Brain Offer New Avenue for Epilepsy Research and Possible Treatment

Aug. 19, 2016 — A child with absence epilepsy may be in the middle of doing something—she could be dancing, studying, talking—when all of a sudden she stares off into space for a few moments. Then, as quickly as ... read more
