Epigenetics
The study of changes in gene expression that do not involve changes to the DNA sequence, influenced by environmental factors.
Nature vs. Nurture
Epigenetics illustrates the interaction between genetics (nature) and environmental influences (nurture) in shaping individual traits.
Genetic Predisposition
An increased likelihood of developing a condition based on genetics, modulated by environmental factors.
Twin Studies
Research involving identical twins that helps distinguish between genetic and environmental influences on behavior and traits.
Brain Plasticity
The brain's ability to change and adapt in response to experience, learning, or injury.
Prefrontal Cortex
The front part of the frontal lobe involved in decision-making, impulse control, planning, reasoning, and social behavior.
Phineas Gage
A railroad worker who suffered a severe brain injury, leading to significant personality changes that highlighted the role of the prefrontal cortex in impulse control.
Corpus Callosum
A bundle of nerve fibers that connects the brain’s two hemispheres, facilitating communication between them.
Split Brain Procedure
Surgical severing of the corpus callosum, used to treat severe epilepsy, affecting communication between the hemispheres.
Hemispherectomy
Surgical removal of one hemisphere of the brain, often performed on children due to greater brain plasticity.
Major Brain Regions - Hindbrain
Controls basic vital functions.
Major Brain Regions - Midbrain
Processes sensory information and controls reflexes.
Major Brain Regions - Forebrain
Involved in mental processes, including the cortex and subcortex.
