Concept
The diaphragm is a crucial muscle that plays a vital role in respiration by contracting and flattening to increase the thoracic cavity volume, thereby drawing air into the lungs. Its function is also integral in maintaining intra-abdominal pressure, aiding in processes like vomiting, defecation, and childbirth.
Relevant Fields:
Concept
The default mode network (DMN) is a group of interconnected brain regions that show increased activity during rest and mind-wandering, playing a crucial role in self-referential thought, memory, and future planning. Disruptions in the DMN are linked to various neurological and psychiatric disorders, highlighting its importance in understanding brain function and mental health.
Concept
Functional connectivity refers to the statistical dependencies or correlations between different regions of the brain, suggesting that these areas are working together during specific cognitive tasks or resting states. It is a crucial aspect of understanding brain networks and is often studied using techniques like functional MRI to map out these interactions and their role in various neurological conditions.

Concept
Neuroimaging encompasses a variety of techniques that visualize the structure and function of the brain, aiding in the diagnosis and research of neurological and psychiatric disorders. It provides critical insights into brain activity, connectivity, and abnormalities, enhancing our understanding of the brain's role in behavior and cognition.
Concept
Cognitive Neuroscience is an interdisciplinary field that explores the neural mechanisms underlying cognitive processes, integrating insights from psychology, neuroscience, and computational modeling. It aims to understand how brain function gives rise to mental activities such as perception, memory, language, and decision-making.
Concept
Brain networks refer to the interconnected neural circuits that facilitate communication and coordination across different regions of the brain, enabling complex cognitive, sensory, and motor functions. Understanding these networks is crucial for deciphering how the brain processes information and how disruptions can lead to neurological and psychiatric disorders.
Concept
Concept
Neural oscillations are rhythmic or repetitive patterns of neural activity in the central nervous system, crucial for various cognitive functions such as perception, attention, and memory. These oscillations facilitate communication between different brain regions by synchronizing neural activity, enabling efficient information processing and integration.
Concept
Basal activity refers to the inherent level of activity or function exhibited by a biological system or organism in the absence of external stimuli or stressors. It serves as a baseline measurement, crucial for understanding deviations caused by experimental treatments or environmental changes.
Concept
Alpha waves are a type of brainwave pattern that occur when a person is awake but in a relaxed state, typically with a frequency range of 8-12 Hz. They are associated with relaxation, meditation, and a decrease in stress, often serving as an indicator of the brain's transition from waking to restful states.
