You just move like a mouse, or do so abnormally like a mutant mouse

The brain is no longer a mysterious black box. Elucidation of the
human genome
is having a profound impact on the understanding of brain function in
health and
disease. However, genes cannot be systematically manipulated in
humans, and this
is why animal models of human functions are being developed.

Now that the human and mice genome sequences are known, unprecedented
opportunities arise for the advancement of psychology and psychiatry.
But there
are some fundamental limitations: while much of psychology and
psychiatry relies
on the evaluation of questionnaires and self-reports, mice are
notoriously
non-compliant with these.

Decoding the dictionary: Study suggests lexicon evolved to fit in the
brain

The latest edition of the Oxford English Dictionary boasts 22,000
pages of
definitions. While that may seem far from succinct, new research
suggests the
reference manual is meticulously organized to be as concise as
possible - a
format that mirrors the way our brains make sense of and categorize
the
countless words in our vast vocabulary.

Young children rely on one sense or another, not a combination,
studies find

Unlike adults, children younger than eight can't integrate different
forms of
sensory input to improve the accuracy with which they perceive the
world around
them, according to a pair of studies reported online in Current
Biology on May
1st.

The findings suggest that the perceptual systems of developing
children might
require constant recalibration-through the use of one sense to fine-
tune another
and vice versa, according to the researchers. They might also reflect
inherent
limitations of the still-developing brain.
