Free will vs. determinism
It is strongly determinist as it views behavior as caused entirely by biological factors over which individuals have no control.
Nature vs. nurture
The biological approach is firmly on the nature side of the debate; however, it does recognize that our brain is a plastic organthat changes with experience in our social world, so it does not entirely deny the influence of nurture. Cross-cultural researchinvolves studying a particular behavior (e.g., gender, facial expressions) across different cultures. If the behavior is found to be similar across cultures, psychologists conclude that differences in behavior are biologically (i.e., nature)...
Holism vs. reductionism
The biological approach is reductionist as it aims to explain all behavior by the action of genetic or biochemical processes. It neglects the influence of factors such as early childhood experiences, conditioning, or cognitive processes.
Twin studies provide geneticists with a kind of natural experiment in which the behavioral likeness of identical twins (whose genetic relatedness is 1.0) can be compared with the resemblance of dizygotic twins (whose genetic relatedness is 0.5). In other words, if heredity (i.e., genetics) affects a given trait or behavior, then identical twins sho...
It is important to appreciate that the human brainis a highly complicated piece of biological machinery. Scientists have only just “scratched the surface” of understanding the many functions of the workings of the human brain. The brain can influence many types of behavior. In addition to studying brain-damaged patients, we can find out about the w...
The Voyage of the Beagle(1805 – 1836) – Darwin formulated his theory of natural selection by observing animals while traveling the world. Harlow (1848): Phineas Gage brain injury case studyprovides neuroscience with significant information regarding the working of the brain. Darwin (1859) publishes On the Origin of Species by Means of Natural Selec...
Aug 17, 2023 · Brain plasticity, also known as neuroplasticity, is the brain’s biological, chemical, and physical capacity to reorganize its structure and function. Neuroplasticity occurs due to learning, experience, and memory formation or due to damage to the brain. Learning and new experiences cause new neural pathways to strengthen, whereas neural ...
Chromosomal Rearrangements. A chromosomal rearrangement means that pieces of chromosomes are missing, duplicated (there are extra copies), or moved around. The effects vary. They depend on which chromosome pieces are involved and how they are rearranged. Some have no effect, some are incompatible with life, and others are somewhere between.

Dec 30, 2022 · (A) rearrangement of α chain and (B) β chain (C) protein structure of TCR. The enzyme that produces this diversity is a complex called the V(D)J recombinase. The recombination occurs in two parts: first double-stranded breaks are made at re- combination signal sequence (RSS) sites, then the breaks are repaired by the general double-stranded break repair mechanism.
