Study Notes
Introduction to Neuroscience
- Neuroscience is the science of the brain and nervous system.
The Nervous System
- The nervous system is the main controlling and communicating center 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 provides higher cognitive functions, such as memory, learning, thinking, planning, decision making, social cognitive processes, motivation, and emotions.
Central and Peripheral Nervous System
- The nervous system consists of the central nervous system (CNS) and peripheral nervous system (PNS).
- The CNS includes the brain and spinal cord, while the PNS includes nerves that connect the CNS to the rest of the body.
What Neuroscientists Do
- Neuroscientists study the nervous system at different levels of inquiry, including:
- Behavioral level: studying the neural basis of behavior.
- System level: studying the various parts of the nervous system.
- Local circuit level: studying the function of groups of neurons.
- Single neuron level: studying what individual neurons do.
- Synapse level: studying what happens at the synapse.
- Membrane level: studying what happens at ion channels on a neuronal membrane.
- Genetic level: studying the genetic basis of neuronal function.
Why Medics Should Learn About Neuroscience
- Neurological disorders are extremely common, accounting for one in eight consultations in general practice and 20% of medical emergency admissions.
- A wide range of medical doctors still lack knowledge and skills in clinical neuroscience.
Nervous System Disorders
- Can be caused by internal or external factors, including:
- Vascular problems, congenital problems, brain tumors, thyroid dysfunction, and high or low blood sugar (internal causes).
- Exposure to toxins, infections, overuse of drugs, trauma, and nutritional deficiencies (external causes).
- Examples of nervous system disorders include:
- Gradual loss of function (degenerative): Parkinson's disease, Huntington's disease, Alzheimer's disease, peripheral neuropathies, and amyotrophic lateral sclerosis.
- Acute problems: stroke, subarachnoid hemorrhage, transient ischemic attack, seizures, and mental health issues.
- Neurodevelopmental problems: autistic spectrum disorders, dyslexia, and other developmental disorders.
Brain Structure and Function
- The brain is made up of billions of brain cells and trillions of connections.
- The brain regions include:
- Frontal lobe
- Thalamus
- Midbrain
- Pons
- Medulla oblongata
- The brain fits into the cranium, with the cerebral cortex divided into four lobes: frontal, parietal, temporal, and occipital.
Meninges and CSF Circulation
- The meninges are protective coverings of the brain and spinal cord, consisting of:
- Dura mater (outermost)
- Arachnoid mater (middle)
- Pia mater (innermost)
- The middle meningeal artery is a branch of the maxillary artery that supplies the dura mater and calvaria.
- The Circle of Willis is a critical structure for cerebral blood flow.
- Cerebrospinal fluid (CSF) is formed in the ventricles, circulates through the subarachnoid space, and is re-absorbed into the systemic veins.
Brainstem and Cranial Nerves
- The brainstem connects the brain to the spinal cord.
- The spinal cord is protected by meninges, including the dura mater, arachnoid mater, and pia mater.
