The somatic nervous system (SNS) is the part of the peripheral nervous system that controls voluntary movement and processes external stimuli through two types of neurons: motor neurons (activating muscles) and sensory neurons (relaying information to the central nervous system).| Simply Psychology
Stress is a biological and psychological response experienced upon encountering a threat that we feel we do not have the resources to deal with.| Simply Psychology
Serotonin is a neurotransmitter primarily found in the brain, intestines, and blood. In psychology, serotonin plays a significant role in mood regulation, emotional well-being, sleep, appetite, and cognitive functions. Abnormalities in serotonin levels or its neural pathways are often associated with mood disorders like depression and anxiety.| Simply Psychology
Mindfulness is a way of paying attention to the present moment on purpose and without judgment. It's a way of training your mind to be more aware and less reactive.| Simply Psychology
The peripheral nervous system (PNS) is critical for connecting the central nervous system (CNS) to the rest of the body. It is essential for bodily functions such as movement, sensation, and autonomic processes.| Simply Psychology
Dopamine is a neurotransmitter in the brain associated with pleasure, reward, motivation, and motor control. In psychology, it's linked to feelings of gratification and is implicated in mood disorders, addiction, and certain behaviors when its levels are imbalanced.| Simply Psychology
Neurotransmitters are chemical messengers that play a vital role in how your brain and body communicate. They affect everything from your mood and memory to your heartbeat and breathing.| Simply Psychology
The Central Nervous System (CNS) consists of the brain and spinal cord. It acts as the body's control center, processing sensory information and directing responses. The CNS coordinates both voluntary activities, like movement, and involuntary ones, such as breathing and heartbeat.| Simply Psychology
The sympathetic nervous system is a branch of the autonomic nervous system that prepares the body for "fight or flight" responses during stressful situations. It increases heart rate, dilates pupils, and inhibits digestion, among other functions, to mobilize the body's resources for immediate action.| Simply Psychology
The parasympathetic nervous system is a subdivision of the autonomic nervous system (ANS), which regulates bodily functions outside of voluntary control, therefore being automatic. It is also called the ‘rest and digest' system as it conserves the body’s natural activity and relaxes the individual once an emergency has passed. It promotes relaxation, energy conservation, and recovery by slowing the heart rate, stimulating digestion, and facilitating other processes when the body is restin...| Simply Psychology
The limbic system is a complex set of brain structures involved in emotion, motivation, memory, and behavior regulation. Key components include the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus. It's central to emotional processing, memory formation, and various autonomic functions, bridging higher cognitive processes and primal emotions.| Simply Psychology
Anxiety disorders are characterized by distressing, persistent anxiety and are often paired with unhelpful behaviors that individuals may use to try to reduce anxiety, such as avoidance or other safety behaviors.| Simply Psychology
The fight or flight response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It prepares your body to either confront or flee from the threat by triggering changes like increased heart rate, quickened breathing, and heightened alertness.| Simply Psychology
