Study Notes
Brain Development
- Brain development starts with a neural plate, folds, and groove, progressing to a neural tube.
- The rostral portion of the neural tube becomes the brain.
- The caudal portion of the neural tube forms the spinal cord.
Primary Brain Vesicles
- Prosencephalon
- Mesencephalon
- Rhombencephalon
Secondary Brain Vesicles
- Telencephalon and diencephalon in forebrain
- Midbrain remains undivided
- Metencephalon and myelencephalon in hindbrain
Major Brain Flexures
- Cephalic (midbrain) and cervical flexures
- Pontine flexure
- Flexures facilitate brain growth within the cranium, bending the forebrain toward the brain stem.
Ventricles of the Brain
- Extensions of the embryonic neural canal.
- Continuous with each other and the central canal of the spinal cord.
- Filled with cerebrospinal fluid (CSF).
- Lined with ependymal cells.
Brain Coverings (Meninges)
-
Dura mater
-
Arachnoid
-
Pia mater
-
Meningitis is an inflammation of the meninges (bacterial or viral).
Anatomy of the Brain
- Telencephalon
- Diencephalon
- Mesencephalon
- Metencephalon
- Myelencephalon
Telencephalon (Cerebrum)
- Largest part of the brain.
- Corpus callosum
- Convolutions (gyri and sulci)
- Fissures (longitudinal and transverse)
Lobes of the Cerebrum
- Frontal lobe
- Parietal lobe
- Occipital lobe
- Temporal lobe
- Insula
Deeper Sulci
- Divide the hemispheres into lobes.
- Central sulcus
- Parieto-occipital sulcus
- Deep lateral sulcus
Functional Areas of the Brain
- Primary motor cortex
- Premotor cortex
- Frontal eye field
- Prefrontal cortex
- Broca's area
- Wernicke's area
- Primary somatosensory
- Somatosensory association
- Primary olfactory
- Primary gustatory
- Primary visual
- Visual association
- General interpretation area
Diencephalon
- Thalamus
- Epithalamus
- Hypothalamus
Mesencephalon
- Corpora quadrigemina
- Red nuclei
- Substantia nigra
Metencephalon
- Cerebellum
- Pons
Myelencephalon
- Medulla oblongata
Limbic System
- Emotional or affective brain
- Located in the medial aspects of cerebral hemispheres and diencephalon
Brain Waves and Sleep (EEG)
- Alpha waves: 8-13 Hz, rest with eyes closed.
- Beta waves: 14-30 Hz, mentally alert, eyes open.
- Theta waves: 4-7 Hz, sleep; abnormal in wakefulness.
- Delta waves: 3-5 Hz, deep sleep.
Sleep Stages
- NREM sleep (75%)
- REM sleep (25%), begins about 90 minutes after sleep onset.
Basal Ganglia
- Caudate
- Lentiform (putamen and globus pallidus)
