To accommodate a lifetime of scents and aromas, mammals have hundreds of genes that each produce a different odorant receptor. The complex and diverse olfactory system they build remains adaptable, but a new study in the journal Science shows that the system's flexibility, or plasticity, has its limits. Working in mice, Brown University scientists found that the fundamental neural wiring map between the nose and the brain becomes established in a critical period of early development and then...

Stowers investigators reveal a developmental switch in targeting capacity of olfactory neurons The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents. In mice the number of odor receptors is closer to 1000. Each olfactory neuron displays only a single type of receptor and all neurons with the same receptors are connected to the same spot, a glomerulus, in the brain. This convergence, or wiring pattern, is often described as an...

Memory Area Of Brain In Older Women Boosted With Regular Aerobic Exercise
2014-04-11 08:42:55

BMJ-British Medical Journal Twice weekly routine may help to slow down advance of dementia, say researchers Regular aerobic exercise seems to boost the size of the area of the brain (hippocampus) involved in verbal memory and learning among women whose intellectual capacity has been affected by age, indicates a small study published online in the British Journal of Sports Medicine. The hippocampus has become a focus of interest in dementia research because it is the area of the brain...

Rat Study Shows Memory Storage During Sleep Can Be Manipulated
2014-04-09 11:21:13

Brett Smith for redOrbit.com - Your Universe Online Previous research has shown that the brain strengthens and maintains recently acquired memories during sleep and a new study has found that introducing new memories to a sleeping brain disrupts these natural cognitive processes. During sleep, the brain shuffles information from short-term to long-term memory. Studies have shown that the "replay" of freshly learned data while asleep plays an essential role in memory. However, it was...

A multidisciplinary group of scientists from the Sanders-Brown Center on Aging at the University of Kentucky have identified an interesting connection between the health of the brain tissue that supports cognitive functioning and the presence of dementia in adults with Down syndrome. Published in the Neurobiology of Aging, the study, which focused on detecting changes in the white matter connections of the brain, offers tantalizing potential for the identification of biomarkers connected...

A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists at UCL and King’s College London. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches. These motor neurons are designed to react to pulses of blue light, allowing scientists to fine-tune muscle control by...

The cerebellum is a section of the brain that is most in charge of cognitive functions and motor skills. Formation and Orientation The cerebellum can be found at the bottom of the brain behind the pons and below that cerebral cortex under a layer of dura mater. It is considered as a part of the "hindbrain". The cerebellum is anatomically divided into two separate hemispheres, marked by the 'vermis', a small midline zone between the left and right hemispheres. But three lobes can be...

Midbrain

The midbrain, also known as the mesencephalon is the part of the brain most responsible for vision, motor control, arousal, temperature regulation, alertness and hearing. Formation and Orientation The midbrain is found under the cerebral cortex and above the hindbrain. The mesencephalon is not divided into any other portions of the brain unlike the other two vesicles that stem from the neural tube. There are four separate lobes on the side of the cerebral aqueduct within the...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
