Oct. 28, 2012 — The ability to learn complex, symbolic math is a uniquely human trait, but it is intricately connected to a primitive sense of magnitude that is shared by many animals, finds a study recently published by the Proceedings of the National Academy of Sciences (PNAS).
Last Updated: 3/21/2013 13:09 PST As many people hit middle age, they often start to notice that their memory and mental clarity are not what they used to be. We suddenly can't remember where we put the keys just a moment ago, or an old acquaintance's name, or the name of an old band we used to love. As the brain fades, we euphemistically refer to these occurrences as "senior moments." While seemingly innocent, this loss of mental focus can potentially have a detrimental impact on our professional, social, and personal well-being.

A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another. [ 1 ] [ 2 ] [ 3 ] Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting. Such neurons have been directly observed in primate and other species including birds . In humans, brain activity consistent with that of mirror neurons has been found in the premotor cortex , the supplementary motor area , the primary somatosensory cortex and the inferior parietal cortex . The function of the mirror system is a subject of much speculation. Many researchers in cognitive neuroscience and cognitive psychology consider that this system provides the physiological mechanism for the perception/action coupling (see the common coding theory ). [ 3 ] They argue that mirror neurons may be important for understanding the actions of other people, and for learning new skills by imitation.
Behavioral neuroscience , also known as biological psychology , [ 1 ] biopsychology , or psychobiology [ 2 ] is the application of the principles of biology (in particular neurobiology ), to the study of physiological , genetic, and developmental mechanisms of behavior in human and non-human animals. It typically investigates at the level of nerves, neurotransmitters, brain circuitry and the basic biological processes that underlie normal and abnormal behavior. Most typically, experiments in behavioral neuroscience involve non-human animal models (such as rats and mice, and non-human primates) which have implications for better understanding of human pathology and therefore contribute to evidence-based practice .
