Researchers at Stanford University are working on figuring out how it happens.   In their study, published in the journal Brain Structure and Function, scientists in Dr....

How the brain works and how the brain is affected by disease are mysteries in large part because neurons are so dynamic, numerous, and complex. Neurolucida 360, a revolutionary, new software product from MBF Bioscience, enables neuroscientists to uncover more information about neurons at a faster rate.   “Neurolucida 360 is a technological revolution” says Jack Glaser, President of MBF Bioscience. “It is the state-of-the-art tool for neuroscientists to analyze...

  With some exceptions, humans and animals prefer to live in an environment free of filth. We clean our bodies and our homes so we can live healthy and productive lives. It turns out, the brain does too.   Researchers at the University of Rochester discovered that the brain cleans itself during sleep—explaining one of the major reasons we partake in a nightly ritual that has mystified scientists...

Scientists discovered that inactivity makes brain cells grow, but not in a good way. In a study published in the Journal of Comparative Neurology, researchers found more neuronal branching in sedentary rats compared to active rats. The growth occurred in a region of the brain that controls blood pressure, leading the scientists to hypothesize that these changes may be part of the reason inactivity is...

The loss of cholinergic neurons is one of the earliest pathological events of Alzheimer’s disease. Cholinergic neurons in the basal forebrain supply the cerebral cortex with acetylcholine, an important neurotransmitter that plays a role in learning, memory, and attention. Details about the function and organization of basal forebrain (BF) neurons are not well understood, but Dr. Laszlo Zaborszky has recently uncovered new information about the...

  Gaunt facial features and a frighteningly thin figure are physical hallmarks of anorexia nervosa, an eating disorder that predominantly affects adolescent girls. But in addition to extreme weight loss, changes take place that aren't as visually apparent. For the first time, scientists in New York have found evidence of brain plasticity in the activity-based anorexia (ABA) mouse model.   Led by Dr. Chiye Aoki of New York...

Scientists hypothesize that during puberty, experiences influence brain development in ways that shape brain structure and even behavior in adulthood. One type of experience that often arises in the minds of pubescent teens and adolescents is sex. But a study published in the journal Hormones and Behavior suggests engaging in sexual activity too soon could be detrimental to the adult brain, and may lead to...

A new optical clearing agent developed by scientists in Japan clears brain tissue samples with greater transparency and less time than other clearing agents, according to a paper published in Nature Neuroscience.   “Combined with two-photon microscopy, SeeDB allowed us to image fixed mouse brains at the millimeter-scale level,” say the authors, who after clearing the brain tissue with SeeDB, captured images with a multiphoton Olympus microscope,...

Researchers at the Stanford University School of Medicine have found that formoterol ̶  an FDA-approved drug for treating asthma and similar respiratory disorders ̶  improves cognitive function in mice genetically altered to exhibit symptoms of Down syndrome including cognitive disability.   Formoterol was chosen for the study because it activates β2 adrenergic receptors (β2ARs) on neurons, a task also carried out by norepinephrine, a neurotransmitter with a...

In spring, days grow long, and the white-footed mouse looks for a mate. For some mammals, day length prompts behaviors like breeding or camouflaging, and scientists say it's not just the arc of the sun that kicks off these seasonal events; substances in the brain also play a part.   One important element is melatonin, a hormone that the mammalian brain secretes at night. According to a...
