Study Notes
Vertebrate Brain Structure
- Vertebrates have a spinal cord and a segmented brain.
- The brain is the central nervous system's core.
- Cephalization is the concentration of brain functions in the head.
Brain Divisions
- The vertebrate brain is divided into three main parts:
- Hindbrain (rhombencephalon): Controls essential functions like respiration and heartbeat.
- Mylencephalon
- Metencephalon
- Cerebellum (balance, coordination, smooth movement)
- Medulla oblongata
- Pons
- Midbrain (mesencephalon): Links hindbrain and forebrain sensory, motor, and integrative components.
- Tectum (dorsal, receives visual and somatosensory, auditory senses)
- Tegmentum (ventral, gateway for sensory/motor information to/from forebrain)
- Isthmus (transitional area between midbrain and hindbrain)
- Forebrain (prosencephalon):
- Diencephalon
- Thalamus
- Hypothalamus
- Pineal gland
- Pituitary gland
- Telencephalon
- Pallium (cerebrum)
- Hippocampus
- Amygdala (homologous structures across vertebrates)
- Diencephalon
- Hindbrain (rhombencephalon): Controls essential functions like respiration and heartbeat.
Mammalian Cerebral Cortex
- Mammalian cerebral cortex arose from the dorsal pallium of other vertebrates.
- It is organized into areas, layers, and columns.
- These areas process sensory information.
- Layers are composed of different neurons.
Associative Areas
- The frontal lobe has Broca's Speech area
- Temporal lobe has Wernicke's area for Comprehension
- Hippocampus plays a role in spatial memory and converting short-term to long-term memory.
- Amygdala is responsible for emotional memories
- Basal Ganglia involved in learning & motor control.
- Visual information from the retina passes through the optic tract, LGN and then to the primary visual cortex for processing.
- Birds have visual association areas in their pallium.
- Olfactory bulbs are crucial for the sense of smell, and their size can indicate keen sense of smell (e.g., T. Rex, Turkey Vultures).
