Novelty directly activates the dopamine system and enhances associative learning. The findings have implications for the development of new machine learning technologies and educational strategies.
A new study backs up existing evidence that maternal immune activation can impact brain development in children. Researchers report immune activation during pregnancy or soon after birth can cause alterations to brain networks associated with social behavior, resulting in autism-like symptoms in the offspring.
Researchers have identified specific neurons and networks that regulate 'sundowning', a phenomenon commonly seen in Alzheimer's patients who exhibit worsening confusion and aggression levels at the end of the day.
Researchers have optimized optogenetics to map the neural circuits of the rodent brain with single neuron resolution.
Using optogenetics to dampen delta waves of rats during sleep resulted in weaker memory reactivation and promoted forgetting. The findings could have significant implications for treating PTSD in humans.
Researchers have created a new tool that could revolutionize optogenetics research.
Researchers have identified a population of neurons in the brainstem which are essential for mice to stop their locomotion.
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.
Researchers discover a link between neural activity in the lateral hypothalamus and the state of REM sleep.
