The human brain: Detective of auditory and visual change
The human brain is capable of detecting the slightest visual and auditory changes. Whether it is the flash of a student’s hand into the air or the faintest miscue of a flutist, the brain instantaneously and effortlessly perceives changes in our environment.

Are Whales Smarter Than We Are?
Cetacean brains, such as those of dolphins (left) and humpback whales (right), have even more cortical convolutions and surface area than human brains do.

Daytime sleep improves memory consolidation
A ninety minute daytime nap helps speed up the process of long term memory consolidation, a recent study conducted by Prof. Avi Karni and Dr. Maria Korman of the Center for Brain and Behavior Research at the University of Haifa found.

Novel Mechanism For Long-term Learning Identified
Practice makes perfect -- or at least that's what we're told as we struggle through endless rounds of multiplication tables, goal kicks and piano scales -- and it seems, based on the personal experience of many, to be true. That's why neuroscientists have been perplexed by data showing that at the level of individual synapses, or connections between neurons, increased, repetitive stimulation might actually reverse early gains in synaptic strength.

Ageing makes the imagination wither
Old age does more than stealthily steal away our most cherished memories: it also seems to diminish our ability to imagine things.

Why Seniors Say "When" Too Soon
Thirsty old folks drink less water than parched whippersnappers because their brains are more easily satisfied, according to a new study. The findings suggest that the brain's satiation mechanisms malfunction as we age and might help explain why seniors are at greater risk for dehydration.

Cause and Treatment for Parkinson's "In Our Sights"

Gerbils can distinguish 'me' from 'you'
If you say something to a gerbil, will it understand? Two researchers have succeeded in training gerbils to recognize human vowel sounds, and have found that they can easily distinguish, say, an 'oo' (as in 'you') from an 'ee' (as in 'me').

Blind humans lacking rods and cones retain normal responses to nonvisual effects of light
In addition to allowing us to see, the mammalian eye also detects light for a number of “non-visual” phenomena. A prime example of this is the timing of the sleep/wake cycle, which is synchronized by the effects of light on the circadian pacemaker in the hypothalamus.
