Furthermore, neuroscience is at the frontier of investigation of the brain and mind. The study of the brain is becoming the cornerstone in understanding how we perceive and interact with the external world and, in particular, how human experience and human biology influence each other. It is likely that the study of the brain will become one of the central intellectual endeavors in the coming decades.

Neuronal development: In a study conducted by Oxford University, on January 11th 2007, found that in comparison of 8 adult and newborn brains, that the newborns had almost double (11.6 million) the amount of neurons than in adults (6.43 million), wheras counts in glial cells in adults (32 million), showed almost triple the number of those in children (10.3 million). [1]
Neurotransmission:More than a 100 neuropeptides identified in the honey bee brain. Researchers at the University of Illinois have reported these in the journal Science. They hope that this will lead to better insight into their complex social behavior [2]
Cognitive neuroscience:Erotic images potently elicit unconscious brain activity. In a study published in the journal PNAS, researchers have demonstrated that the brain is able to unconsciously pick out and respond to erotic images even when noise suppresses their conscious knowledge. [3]
Molecular neuroscience:Link between the genetics and pathology of Rett syndrome uncovered. In a study published in the journal Neuron, researchers have discovered a possible mechanism by which the inherited mutation in this disease selectively targets neurons. Rett syndrome is a leading cause of mental retardation in females.[4]
