Researchers at MIT have discovered that Sirtuin1, a protein encoded by the SIRT1 gene, promotes synaptic plasticity and boosts memory.
SIRT1 was again found to be important in learning and memory for mice, but boosting SIRT1 above the normal levels of expression did not lead to an improvement in learning and memory.
A new study from researchers at UCLA indicates that new memories with emotional content can be formed even if the amygdala is damaged. Researchers believe that other areas compensated for the damaged amygdala, and aided learning and memory.
UCL neuroscientists have shown that a single neuron, and even a single dendrite, can respond differently to unique sequences of input.
This research shows that the loss of connections in the corpus collosum could be partly responsible for slower response times seen in older animals and humans due to too much crosstalk and confusion between the brain hemispheres.
Neuroscientists at UC Berkeley have discovered that stimulation of a certain area of the brain can cause a change in which hand a person favors to perform a task. Using transcranial magnetic stimulation on right handed test subjects, researchers discovered that stimulating the posterior parietal cortex on the left side caused an increase in the use of the left hand. Researchers suggested this finding might be useful in discovering methods to help patients overcome learned limb disuse.
Recent visual neuroscience research provides evidence that blind people process the sense of touch faster than people with normal vision. The research also found that each blind person's tactile perception time was nearly equal to their average speed of their finger moving from one Braille character to the next.
Neuroscience research involving epileptic patients with brain electrodes surgically implanted in their medial temporal lobes shows that patients learned to consciously control individual neurons deep in the brain with thoughts.
Computational neuroscience research provides new information on the N-type calcium channel and synaptic transmission. The computational neuroscience model investigated shows that a single open N-type calcium channel's current may be sufficient to enable neurotransmitter release.
Zif proteins have been found to control whether a brain stem cell differentiates into a neuron or renews as a brain stem cell. There are Zif related proteins in humans that may be targeted by new treatments for brain cancer and other diseases.
New research on learning describes the interaction between acetlycholine receptors and SK channels and their involvement in learning and memory. These findings could lead to new research targeting acetylcholine and SK channels to help cognitive disorders such as Alzheimer's disease and schizophrenia as well as help understand learning and memory better.
