Study Notes
Introduction to Neuroscience
- Neuroscience is the study of the brain and nervous system
- It involves understanding the functions of the nervous system at different levels: behavioural, system, local circuit, single neuron, synapse, membrane, and genetic
The Nervous System
- The nervous system is the main controlling and communicating centre of the body
- It coordinates and controls all essential bodily functions, processes information from the environment, and enables the body to respond accordingly
- The nervous system consists of the central nervous system (CNS) and peripheral nervous system (PNS)
- The autonomic nervous system (ANS) is a subdivision of the PNS that controls involuntary actions
Neuroscientists and Their Work
- Neuroscientists study the nervous system at different levels to understand its functions and disorders
- They investigate the neural basis of behaviour, various parts of the nervous system, local circuits, single neurons, synapses, and genetic factors
Importance of Neuroscience in Medicine
- Neurological disorders are extremely common and account for one in eight consultations in general practice
- 20% of medical emergency admissions are due to neurological disorders
- Doctors should learn about neuroscience to better understand and manage these disorders
Nervous System Disorders
- Disorders can be caused by internal (vascular problems, congenital problems, brain tumours, etc.) or external factors (toxins, infections, trauma, etc.)
- Examples of gradual loss of function include degenerative diseases such as Parkinson's, Huntington's, Alzheimer's, and multiple sclerosis
- Acute problems include stroke, seizures, and mental health issues like anxiety, depression, and psychosis
- Neurodevelopmental problems include autistic spectrum disorders and dyslexia
Brain Development and Function
- The brain is shaped by experiences and environment
- It is responsible for our perceptions, emotions, and actions
- The brain needs other people to function properly, and technology is changing what it means to be human
Brain Structure and Function
- The brain has different regions, including the frontal lobe, thalamus, midbrain, pons, and medulla oblongata
- The cerebral cortex has four lobes: frontal, temporal, parietal, and occipital
- The limbic system is a network of structures involved in emotion, motivation, and memory
The Cranium and Brain
- The cranium protects the brain and is formed by two parts: neurocranium and viscerocranium
- The neurocranium has eight bones, including the frontal, ethmoidal, sphenoidal, and occipital bones
- The viscerocranium consists of facial bones, including the mandible and vomer
- The brain fits into the cranium, with different regions fitting into specific areas of the skull
Meninges and CSF Circulation
- The meninges are three layers of protective tissue covering the brain and spinal cord: dura mater, arachnoid mater, and pia mater
- The middle meningeal artery supplies the dura mater and calvaria
- The circle of Willis is a network of arteries that supply the brain
- Cerebrospinal fluid (CSF) is formed in the ventricles and circulates through the subarachnoid space before being reabsorbed into systemic veins
