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
Obsessive-Compulsive Disorder (OCD) is a mental health condition characterized by persistent, unwanted thoughts, urges, or images (obsessions) and repetitive behaviors or mental acts (compulsions) that an individual feels driven to perform to relieve anxiety or distress caused by these obsessions.| Simply Psychology
In psychology, the hippocampus is a crucial structure within the brain's medial temporal lobe. It plays a vital role in forming and retrieving memories, spatial navigation, and emotional responses. Damage to the hippocampus can lead to memory impairments and difficulty forming new memories, highlighting its importance in learning and cognition.| 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 amygdala is a complex structure of cells nestled in the middle of the brain, adjacent to the hippocampus (which is associated with memory formation). It is part of the limbic system and plays a key role in processing emotions and emotional reactions.| 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
Positive reinforcement is a basic principle of Skinner's operant conditioning, which refers to the introduction of a desirable or pleasant stimulus after a behavior, such as a reward.| 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 brain's reward system is a network of structures responsible for pleasure, motivation, and reinforcement learning. Central to this system are the Ventral Tegmental Area (VTA) and the Nucleus Accumbens (NAc). When a rewarding stimulus is perceived, dopamine is released from the VTA, acting on the NAc, leading to feelings of pleasure. Dysfunctions in this pathway can underlie addiction and other behavioral disorders.| Simply Psychology
