Brain's Filing System Uncovered

...e advanced online Nature that they have identified neurons that assist in categorizing visual stimuli. They found that the activity of neurons in a part of the brain called the parietal cortex encode the category, or meaning, of familiar visua...

Discerning Sour Taste

...olution, the researchers suspected that the spinal neurons with PKD2L1 might be responsible for monitoring th.... Electrical recordings taken from these spinal neurons showed that they were able to detect and respond to very small changes in pH, confirming their role ...

Cooling Temperatures Help Crucian Carp

...to transmit information among cells, including the neurons in the brain. The quieter the pumps, the less active and energy-consuming the brain is. However, if the pumps shut down, the cells die. Glycogen, the form in which the body stores carbohydrates, is the energy supply that vital organs such as the hea...

Scientists Claim Encouraging Progress On Hereditary Diseases

...development of new stem cell lines. These lines of neurons - or brain cells - could also benefit patients and could potentially be used as a reliable and renewable source of tissue for cell replacement therapy. Interesting and promising pilot research findings were presented using high dose creatine as a the...

A Human Brain Gene Could Hold Clues On The Evolution Of Brain Capacity

...ucture of the human cerebral cortex. Cajal-Retzius neurons release a protein called reelin that guides the growth of neurons and the formation of connections among them. HAR1F is active at the same time as the reelin gene. ...

Long-life genes - A new way to combat cancer…

...ed by cells in the reproductive system and sensory neurons in the brain. In the study, the team mutated a tumor suppressor gene called gld-1 in the worms, causing cells in the animals' gonads to divide rapidly and form germ-line tumors. These tumor cells, when left undisturbed, break out of the gonad and f...

Human Brain Cells Might Have The Self Potential For Healing

Treating Depression may Raise Anxiety Levels

...l approach and see what chronic stress does to the neurons in amygdala which is the centre of emotions." The researchers found that, in the chronically stressed transgenic mice, BDNF acted as an antidepressant and prevented damage to the hippocampus as expected. However, over expression of BDNF in amygdala...

Targeting PARP1 Is Effective In Protecting HD Cells from Damage

...he current study. ‘It has recently been shown that neurons from patients with Huntington's appear to be energy-deficient, so we hypothesized that modest stresses that would be tolerated by healthy cells could send HD cells below a viable energy threshold and that blocking PARP1 activation could be protective...

PKG in the On Position Results in Chronic Pain

...the molecular level a pain stimulus occurs and the neurons becomes excited and begin to send signals to the brain and the individual sense pain but when the stimulus is removed the nerves become dormant and there is no sense of pain. In case of patients suffering from chronic pain the nerves remain the hyper...

Diagnosing Schizophrenia

...terns in large amounts of data in a similar way to neurons in the brain. Browne trained his network on the measurements of 17 of the volunteers to teach it which of the data sets corresponded to schizophrenia and which did not. He then asked the program to diagnose the status of the remaining volunteer, ba...

The number decreases as the infants age, dropping back to normal as the young become independent. 'Fatherhood produces ...
