Study Notes
Attention
- Superior Frontal Cortex: Plays a key role in maintaining focus, controlling voluntary movements, and holding information in short-term memory.
- Posterior Parietal Cortex: Integrates sensory information with motor commands for spatial awareness, allowing us to navigate our environment and focus on specific areas.
- Ventral Prefrontal Cortex: Processes risk and fear, evaluates emotional responses, and assigns emotional value to stimuli.
- Temporoparietal Junction (TPJ): Essential for identifying objects of interest and shifting attention, crucial for understanding the perspectives of others.
- Pulvinar of Thalamus: Filters sensory information and enhances visual attention, active during rapid eye movements (saccades).
- Superior Colliculus: Processes new stimuli and facilitates eye movements to focus on visually relevant information.
Cognitive Control
- Lateral Prefrontal Cortex: Executes higher-level cognitive functions like planning, decision-making, and reasoning.
- Frontal Pole: Involved in strategic planning, multitasking, and integrating information from various cognitive processes.
- Orbitofrontal Cortex: Processes rewards and punishments, influencing decision-making and impulse control.
- Medial Frontal Cortex: Associated with decision-making, anticipating rewards, monitoring errors, and self-assessment.
- Primary Motor Cortex: Generates signals for initiating voluntary movements and executes planned actions.
- Secondary Motor Areas: Control complex movements involving sequences of actions, working closely with the premotor cortex.
Social Cognition
- Ventral Medial Prefrontal Cortex: Processes emotional responses and assesses social risks, allowing us to navigate social situations.
- Anterior Cingulate Cortex: Manages emotional regulation, impulse control, empathy, and decision-making in social contexts.
- Posterior Cingulate Cortex: Involved in memory processing and internal thoughts like daydreaming.
- Medial Parietal Cortex (Precuneus): Essential for self-awareness and consciousness during social interactions.
- Dorsolateral Prefrontal Cortex: Supports executive functions like working memory and cognitive flexibility during social interactions.
- Ventral & Ventrolateral Prefrontal Cortex: Processes uncertain risks and emotional decision-making, important for social behavior.
Memory
- Hippocampus: Forms new memories, connecting them with emotions and learning processes.
- Amygdala: Influences memory strength by processing emotions and attaching emotional significance to events.
- Fornix: Main pathway for communication from the hippocampus, essential for memory function.
- Anterior Thalamic Nucleus: Acts as a relay for memory information to the cortex, critical for alertness and memory formation.
- Mammillary Body: Contributes to recognition memory processing, part of the limbic system.
- Medial Temporal Lobe: Houses the hippocampus and other structures critical for converting short-term memories into long-term memories.
- Perirhinal Cortex & Entorhinal Cortex: Connect the hippocampus to the neocortex, crucial for object recognition and memory formation.
- Parahippocampal Cortex: Facilitates memory encoding and retrieval, especially for spatial information.
Emotion
- Orbitofrontal Cortex: Evaluates emotional values and processes rewards, influencing emotional responses.
- Cingulate Gyrus: Manages emotions and autonomic functions, part of the limbic system regulating emotional behavior.
- Thalamus: Acts as a relay for sensory information, supporting attention, alertness, and memory processes associated with emotions.
- Hypothalamus: Regulates emotional behavior and physiological responses to emotional stimuli.
- Amygdala: Develops and processes emotions like fear, and stores memories based on their emotional impact.
- Corpus Callosum: Connects the two hemispheres of the brain, facilitating communication and coordination of emotional responses across the brain.
Language
- Broca's Area: Essential for speech production, damage to this area results in Broca's aphasia, affecting fluency but not comprehension.
- Wernicke's Area: Key for language comprehension, damage to this area results in Wernicke's aphasia, affecting speech comprehension.
- Inferior Frontal Cortex: Involved in language production and reasoning, including Broca's area.
- Superior Temporal Gyrus: Processes auditory information, crucial for understanding language.
- Angular Gyrus: Connected to complex language functions like reading and writing.
- Supramarginal Gyrus: Plays a vital role in phonological processing and language perception.
- Sylvian Fissure: Separates the temporal lobe from the frontal and parietal lobes, crucial for brain structure and function.
