NEUROBIOLOGY & BEHAVIOUR NEUROBIOLOGY OF ANIMAL BEHAVIOUR
Abstract
It is a fairly convoluted affair; all of this is orchestrated by the nervous system, hormones, genes and the environment quarrelling all in the background, causing animal behaviour. In neurobiology we have the privilege of dissecting how of how neurons in the brain and peripheral systems program animals into their feeding, mating, social and migration patterns, and why they sometimes behave in a way which seems completely random to us.
Recent discoveries in neuroscience have demonstrated that behaviour is the result of the structure of the brain, and the tightness with which the circuits are wired. The primary driving force behind the motivation, our mood, learning and managing relationships with others is dopamine, serotonin and a host of other messengers.
Genetics and the environment draw the hammer in on the other end, adjusting the plasticity of the brain, the way we learn, and the way we learn behaviourally to change situations.
The novel laboratory equipment - consider electrophysiology, fMRI, and CRISPR-Cas9-based gene editing - have increased our understanding of the underlying brain circuitry as never before. The idea of this review is to present the entire neurobiological: circuitry, neurotransmitters, hormone regulation, learning and memory, and the interaction of genes and the environment. It is simply about how animals evolve and survive and it leads to the larger enigma of neuroscience, evolution and behavioural ecology.
