Document Summary
Neuroscience encompasses how the nervous system is organized, how they develop and how they generate behaviour. Genetics, genomics, molecular and cell biology, anatomy, systems physiology, behavioural observation and psychology help us nd answers. Sensory systems tell the organism about its own state and the state of its environment. Associational systems link the sensory and motor systems, and provide higher order functions like: perception, attention, cognition, emotions, language, thinking. The brain is the product of gene expression. Genomics: a eld that focuses on the analysis of complete dna sequences (coding and regulatory) 14,000 genes are expressed in the developing and/or mature brain. 8,000 of these are in all cells and tissues. Lots of brain-speci c genetic info is in introns and regulatory sequences. The diversity and complexity of brain function is due to the varying level and location of genes expressed in speci c regions.
