Study Notes
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
