Lysosomes May Contribute to Alzheimer's

New research from Yale University shows lysosomes, the “garbage disposal” systems of cells, can fail and perhaps contribute to Alzheimer’s disease. Lysosomes, the “garbage disposal” systems of cells, are found in great abundance near the amyloid plaques in the brain that are a hallmark of Alzheimer’s disease. Scientists have long assumed that their presence was […]

Scientists Show Multiple Cortical Regions Needed to Process Information

Neuroscientists from MIT show that multiple cortical regions work together simultaneously to process sensorimotor information despite their predetermined specialized roles. Researchers at MIT have proven that the brain’s cortex doesn’t process specific tasks in highly specialized modules — showing that the cortex is, in fact, quite dynamic when sharing information. Previous studies of the brain […]

Recalling Happier Memories to Reverse Depression

By artificially reactivating happy memories that were formed before the onset of depression, MIT neuroscientists have shown that they can cure the symptoms of depression in mice. The findings, described in the June 18 issue of Nature, offer a possible explanation for the success of psychotherapies in which depression patients are encouraged to recall pleasant […]

Pupil Diameter Predicts Task Performance

Researchers from the Yale School of Medicine reveal how changes in the activity of individual neurons during performance of a task correspond exactly to the diameter of the pupil, showing signatures of high arousal for a wide diameter and low arousal for a small diameter. If you want to know who is ready to perform […]

Poor Sleep Linked to Alzheimer’s and Memory Loss

A newly published study from UC Berkeley reveals a new pathway through which Alzheimer’s disease may cause memory decline later in life. UC Berkeley scientists have found compelling evidence that poor sleep — particularly a deficit of the deep, restorative slumber needed to hit the save button on memories — is a channel through which […]

Brain Development During Adolescence in Bipolar Disorder

A newly published study from Yale University shows that key areas of the brain that help regulate emotions develop differently in adolescents with bipolar disorder. In brain areas that regulate emotions, adolescents with bipolar disorder lose larger-than-anticipated volumes of gray matter, or neurons, and show no increase in white matter connections, which is a hallmark […]

Scientists Identify Brain Circuit that Controls Emotional Decisions

A newly published study details how neuroscientists from MIT identified a neural circuit that controls decision-making under conflict. Some decisions arouse far more anxiety than others. Among the most anxiety-provoking are those that involve options with both positive and negative elements, such choosing to take a higher-paying job in a city far from family and […]

New Study Shows How the Brain Responds to Food Cues

A new study set to appear in The Journal Neuroscience illustrates that it is the way the brain responds to food cues when individuals are not hungry that predicts weight gain and that the reasons why people gain weight can be fundamentally different. The way the brain responds while sipping a delicious milkshake can predict […]

Study Shows Extended Space Travel May Warp Astronauts' Brains

A new study from UC Irvine shows that galactic cosmic rays can cause dementia-like symptoms, making extended space trips to locations such as Mars more difficult to accomplish. What happens to an astronaut’s brain during a mission to Mars? Nothing good. It’s besieged by destructive particles that can forever impair cognition, according to a UC […]

Neuroscientists Pinpoint Neurons That Help Primates Tell Faces Apart

Using optogenetics, neuroscientists from MIT have provided the first evidence that directly links FD neurons to face-discrimination in primates — specifically, differentiating between males and females. How do primates, including humans, tell faces apart? Scientists have long attributed this ability to so-called “face-detector” (FD) neurons, thought to be responsible for distinguishing faces, among other objects. […]

Controlling the Thalamus with Dynamic Synapses

Neuroscientists from Brown University show how cells in the brain’s cortex can either stifle or enhance sensory information incoming from the thalamus, thereby allowing it to focus on just some of the many sensory inputs it might choose to consider. Providence, Rhode Island (Brown University) — We consider only some of the sights, sounds, and […]

New Staining Method to Reveal Circuit Diagram of the Brain

Researchers from the Max Planck Institute of Neurobiology have developed a special staining method that brings the reconstruction of all nerve cells and their connections within reach. Learning, it is widely believed is based on changes in the connections between nerve cells. The knowing which nerve cells is connected to which other nerve cell would […]

Experimental Cancer Drug Restores Memory

New research from Yale University reveals that the experimental cancer drug AZD05030 blocks damage triggered during the formation of amyloid-beta plaques, restoring synaptic connections and memory in a mouse model of Alzheimer’s. Memory and as well as connections between brain cells were restored in mice with a model of Alzheimer’s given an experimental cancer drug, […]

Possible Personalized Treatments for More Aggressive Forms of Brain Cancer

New research from Yale University reveals that it may be possible to develop personalized treatments for more aggressive forms of brain cancer. DNA mutations can cause cancer but in some cases, more mutations may mean a better prognosis for patients. A Yale-led comprehensive genomic analysis of more than 700 brain tumors has revealed one such […]

New Technique Could Lead to Long-Lasting Localized Stimulation of Brain Tissue

Using external magnetic fields and injected magnetic nanoparticles, a new technique developed by researchers at MIT could lead to long-lasting localized stimulation of brain tissue without external connections. This video shows a calcium ion influx into neurons as a result of magnetothermal excitation with alternating magnetic fields in the presence of magnetic nanoparticles. Neurons on […]

Cognitive Skills Peak at Different Ages Across Adulthood

New research from neuroscientists at MIT and Massachusetts General Hospital reveals that different parts of the brain work best at different ages. Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline. However, more recent findings, including […]

Study Shows Connection Between Key Autism Risk Genes

A newly published study from Yale University reveals an important connection between key autism risk genes in the human brain, a major step toward understanding how brain development goes awry in some individuals with the disorder. The research shows that CHD8, a gene that is strongly linked to autism, acts as a master regulator in […]

Study Shows Hunger Neurons also Control Compulsive Behaviors

A newly published study from Yale University shows that in the absence of food Agrp neurons trigger foraging and repetitive behaviors in mice. In the absence of food, neurons that normally control appetite initiate complex, repetitive behaviors seen in obsessive-compulsive disorder (OCD), and anorexia nervosa, according to a new study by Yale School of Medicine […]
