There are a number of drugs and experimental conditions that can block cognitive function and impair learning and memory. However, scientists have recently shown that some drugs can actually improve cognitive function, which may have implications for our understanding of cognitive disorders such as Alzheimer's disease. The new research is reported 21 February in the open-access journal PLoS Biology. The study, led by Drs. Jose A. Esteban, Shira Knafo and Cesar Venero, is the result of...

UC Riverside scientists identify a protein that plays a crucial role in learning and memory Biomedical scientists at the University of California, Riverside have identified a new link between a protein called beta-arrestin and short-term memory that could open new doors for the therapeutic treatment of neurological disorders, particularly Alzheimer's disease. Beta-arrestin is expressed in various cells of the body, including cells of the hippocampus, the region of the brain that is...

Inhibition of neighboring nerve cells determines the reaction speed Each part of the body has its own nerve cell area in the brain —we therefore have a map of our bodies in our heads. The functional significance of these maps is largely unclear. What effects they can have is now shown by RUB neuroscientists through reaction time measurements combined with learning experiments and “computational modeling”. They have been able to demonstrate that inhibitory influences of...

Aging-related hearing loss is not set in stone, study finds Age-related delays in neural timing are not inevitable and can be avoided or offset with musical training, according to a new study from Northwestern University. The study is the first to provide biological evidence that lifelong musical experience has an impact on the aging process. Measuring the automatic brain responses of younger and older musicians and non-musicians to speech sounds, researchers in the Auditory...

The research, published in Neuroscience, sheds light on what determines availability of the molecules involved in cardiorespiratory control Researchers at Oregon Health & Science University (http://www.ohsu.edu) have discovered that a molecule critical to the development and plasticity of nerve cells — brain-derived neurotrophic factor (BDNF) -- is severely lacking in brainstem neurons in mutations leading to Rett syndrome, a neurological developmental disorder. The finding has...

Caltech Researchers Identify Mechanism Behind Associative Memory by Exploring Insect Brains A key feature of human and animal brains is that they are adaptive; they are able to change their structure and function based on input from the environment and on the potential associations, or consequences, of that input. For example, if a person puts his hand in a fire and gets burned, he learns to avoid flames; the simple sight of a flame has acquired a predictive value, which in this case, is...

Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories. The findings, published today [13 Dec] in the...

Neuroimaging has provided fascinating insight into the dynamic nature of human brain maturation. However, most studies of developmental changes in brain anatomy have considered individual locations in relative isolation from all others and have not characterized relationships between structural changes in different parts of the developing brain. Now, new research describes the first comprehensive study of coordinated anatomical maturation within the developing human brain. The study,...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
