parts of hindbrain
Myelencephalon
Metencephalon
Hindbrain – Myelencephalon
medulla oblangata
Reticular formation
Cerebellum
Pons
Hindbrain – Myelencephalon: Medulla oblongata
non voluntary activities (heart rate, sneezing, coughing..)
Hindbrain – Myelencephalon: Reticular Formation
100 nuclei with varying functions (sleep, attention, movement, reflexes)
Hindbrain – Myelencephalon: Cerebellum
integrates sensory info from brain and spine to guide motor activity.
Hindbrain – Myelencephalon: Pons
obtains information from body movements and the visual system to control eye movements.
Midbrain – Mesencephalon
Tectum
Tegmentum
Midbrain – Mesencephalon: Tectum
Contains:
two pairs of bumps called colliculi (little hills)
superior colliculi (visual function)
inferior colliculi (auditory function)
Midbrain – Mesencephalon: Tegmentum
Periaqueductal grey – pain and defensive behaviour
Red nulceas & substantia nigra – motor function
Forebrain - Diencephalon
Thalamus
Hypothalamus
Pituitary Gland
Limbic system
Basal Ganglia
Cerabral Cortex
Forebrain - Diencephalon: Thalamus
Receives sensory information and sends it to the relevant parts of the brain
Forebrain - Diencephalon: Hypothalamus
Heavily involved in emotion and motivation (feeding, drinking, and temperature)
Forebrain - Diencephalon: Limbic system
Regulates motivated behaviours
Forebrain - Diencephalon: Basal Ganglia
Striatum (caudate and putamen)
Globus Pallidus (motor and cognitive functions, learning and memory)
Forebrain - Diencephalon: Cerabral Cortex
Involved in higher cognitive processes (language, attention, perception)
2 hemispheres, 4 lobes
The two hemispheres are joined by the corpus callosum
