Example of an external input
Perceptions
Example of internal input
Drives
5 types of analyses
1) Wake/Sleep
2) Attention
3) Learning & Memory
4) Motivation
5) Emotions
Voluntary outputs are
Motor
Involuntary outputs are
Motor & Physiology
T or F: Neurons only connect to the brain
F: neurons only connect to other neurons or muscle/motor plates
T or F: Bigger brains= More neurons= Higher intelligence
True
What are the 3 primary vesicles that arise from the anterior end of the neural tube
Prosencephalon, Mesencephalon, Rhombencephalon
What 2 secondary brain vesicles are the Prosencephalon broken into?
Telencephalon and Diencephalon
Does the mesencephalon give rise to a different secondary brain vesicle?
No, it is still called the Mesencephalon
What 2 secondary brain vesicles does the Rhombencephalon divide into?
Metencephalon and Myelencephalon
What brain structures come from the Telencephalon?
Cerebrum: cerebral hemispheres (cortex, white matter, and basal nuclei)
What brain structure comes from the Diencephalon?
Diencephalon (thalamus, hypothalamus, epithalamus) and and Retina
What structure comes from the Mesencephalon?
Midbrain of the Brain Stem
What structures come from the Metencephalon?
Pons of the Brain Stem and Cerebellum
What structures come from the Myelencephalon?
The Medulla Oblongata of the Brain Stem
What secondary brain vesicle are the lateral ventricles associated with?
Telencephalon
What ventricle is associated with the Diencephalon?
Third ventricle
What adult neural canal region is associated with the Cerebral Aqueduct?
Mesencephalon
What secondary Brain vesicle is associated with the Fourth ventricle?
Metencephalon and Myelencephalon
What structure is the central canal associated with?
Spinal cord
What covers the CNS?
Meninges
