    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.
