Biopsychology

Biopsychology explores the biological foundations of psychology, examining the relationship between psychological processes and physiological events. It …

The nervous system coordinates body functions through its complex network of nerve cells, enabling sensation and movement. The nervous system has two …

Neurons, the excitable cells of the nervous system, specialize in transmitting information through electrical and chemical signals in the body. A neuron …

Neurons communicate by sending electrochemical signals that travel along their axons to neighboring neurons. When the electrical charge within a neuron …

Neurotransmitters act as chemical messengers in the nervous system, essential for communication between neurons. They regulate physiological and …

The brain is divided into three main sections: the forebrain, the midbrain, and the hindbrain. The forebrain is the largest part of the brain and consists …

The human brain cortex is divided into two cerebral hemispheres: the left and the right. The corpus callosum, a robust bundle of neural fibers, connects …

The cerebral cortex consists of four lobes: the frontal, parietal, temporal, and occipital lobes. The frontal lobe situated behind the forehead regulates …

The somatosensory cortex, located in the parietal lobe, plays a crucial role in interpreting sensory information, such as touch, temperature, and body …

The spinal cord begins at the base of the brain and extends down the middle of the back, serving as a vital communication link between the brain and the …

Brain lateralization refers to the tendency of some cognitive processes or neural functions to be more dominant in one hemisphere of the brain than the …

Human genetics explores how genes influence physical traits such as height and eye color, behaviors like risk-taking and eating habits, and susceptibility …

Within the human body, a vast network of trillions of cells functions cohesively. Typically, each cell contains a nucleus with 46 chromosomes,  a …

Genetic variation stems from differences in DNA sequences among individuals, which are essential for species adaptation and evolution. Genetic variations …

Behavior genetics explores the role of inheritance in shaping human behavior. Researchers use family, twin, and adoption studies to assess heritability by …

Evolutionary psychology examines how natural selection, a theory proposed by Charles Darwin influences the development of human behavior and mental …

Neuroplasticity is an inherent characteristic of the nervous system to reorganize itself by creating new neural connections in response to factors or …

Brain imaging refers to various techniques used to visualize the structure and activity of the brain. CT scans create three-dimensional images, which are …

The endocrine system is composed of glands that secrete hormones, which are chemical messengers crucial for bodily functions. These hormones circulate …

Hormones are the chemical messengers that coordinate complex processes in the body. Oxytocin is synthesized in the hypothalamus and secreted by the …

Gregor Mendel's principles of inheritance demonstrated how traits are transmitted from parents to offspring and are controlled by distinct units known …

Gene expression is influenced by environmental factors such as radiation, temperature, behavior, nutrition, and stress. The range of reaction suggests …

Heritability measures the genetic influence on traits or physical characteristics such as height or eye color. Heritability can vary depending on the …

Natural selection drives evolution by supporting organisms that are best adapted to their environments, enhancing their survival and reproduction rates. …

The principle of natural selection suggests that organisms better adapted to their environment are more likely to survive and reproduce. Evolutionary …

In a study involving the mating behavior of heterosexual women and men, people posing as strangers complimented students and then proposed casual sex. …
