Neuroscience and Social Perception Quiz

Cortical Processes of Motor Control

• Dorsolateral prefrontal cortex, premotor cortex, primary motor cortex, superior and posterior parietal lobe, and higher visual areas are involved in motor control

The Mirror Neuron System

• The Mirror Neuron System is involved in interpreting social situations and social perception
• Area F5 (inferior premotor cortex) is the human equivalent of monkey F5
• 'Grasping MN' fires when the experimenter is grasping an object and when the monkey is grasping an object, but not when the object is grasped with pliers

Neuroanatomy

• The neocortex of the cerebrum has sulci (grooves) and gyri (convolutions)
• The brain has three main parts: cerebrum, cerebellum, and brainstem (midbrain, pons, and medulla oblongata)
• The meninges are protective membranes around the brain and spinal cord

Ventricles and Neurodegeneration

• Ventricles are cavities in the brain that produce and circulate cerebrospinal fluid
• Enlarged ventricles can be a sign of neurodegeneration in diseases like schizophrenia and Alzheimer's dementia

Neocortex Organization

• The neocortex is organized into 6 layers
• Different areas of the neocortex have specific functional roles
• Brodmann areas (BA) are distinct regions of the neocortex with different functions

Amygdala and Emotions

• The amygdala plays a crucial role in emotions, particularly fear
• The Kluver-Bucy syndrome is a condition where the temporal lobes (including the amygdala) are removed, leading to a lack of fear response and other symptoms

Basal Ganglia and Cortico-Striato-Thalamic Loop

• The basal ganglia control the interaction between the neocortex and diencephalon, influencing cognitive functions and motivation
• The cortico-striato-thalamic loop is a network involved in motor control and cognitive functions
• In Parkinson's disease, the cortico-striato-thalamic loop is disrupted, leading to motor symptoms
