UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that the entorhinal cortex behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.
Newly formed emotional memories can be erased from the human brain.The findings may represent a breakthrough in research on memory and fear. This is shown by researchers from Uppsala University in a study being published by Science.
Neuroscientists take the first step toward deciphering the connection between general brain function and emergent behavioral patterns in autism. Study shows that autistic adults have unreliable neural sensory responses to visual, auditory and somatosensory, or touch, stimuli.
UC Irvine scientists have discovered intriguing differences in the brains and mental processes of an extraordinary group of people who can effortlessly recall every moment of their lives since about age 10. Research offers the first scientific findings about nearly a dozen people with this highly superior autobiographical memory (HSAM).
Researchers determined how the neurons and muscles are connected in a decision-making neural network important for mating in C. elegans. The team also accurately measured the weights of those connections, i.e., an estimate of the strength with which one neuron or muscle communicates with another.
Researchers can control the behavior of monkeys by using pulses of blue light to very specifically activate particular brain cells. The findings represent a key advance for optogenetics, a state-of-the-art method for making causal connections between brain activity and behavior. Researchers say that similar light-based mind control could likely also be made to work in humans for therapeutic ends.
A new Caltech study suggests that specific changes in an overactive immune system can indeed contribute to autism-like behaviors in mice, and that in some cases, this activation can be related to what a developing fetus experiences in the womb.
Scientists have laid bare a novel molecular mechanism responsible for the major depression symptom, anhedonia, the loss of the ability to experience pleasure. The brain circuit involved in this newly elucidated pathway is largely identical between rodents and humans, upping the odds that the findings point toward new therapies for depression and other disorders. Additionally, opinion leaders hailed the study’s inventive methodology, saying it may offer a much sounder approach to testing new antidepressants.
Honeybees can reverse brain aging and learning deficits when they take on nest responsibilities usually done by younger bees. Findings suggest social interventions may be used to slow or treat age-related dementia.
