1/26/2017 15 Major Structures of the Human Brain
1/26/2017 16 The Hindbrain The Hindbrain – Medulla – First large swelling at the top of the spinal cord, forming the lowest part of the brain ▪ Responsible for life-sustaining functions such as breathing, swallowing, and heart rate
1/26/2017 17 The Hindbrain The Hindbrain – Pons – larger swelling above the medulla that connects the top of the brain to the bottom ▪ Plays a part in sleep, dreaming, left – right body coordination, and arousal
1/26/2017 18 The Hindbrain Medulla Pons The Hindbrain • Reticular formation (RF) • area of neurons running through the middle of the medulla and the pons and slightly beyond – Responsible for selective attention – Coma and death – Fatigue, disrupted sleep, and changes in sexual arousal • Cerebellum • part of the lower brain located behind the pons – Controls and coordinates involuntary, rapid, fine motor movement – Failure of smooth movement
1/26/2017 19 Limbic System The Limbic System • A group of several brain structures located under the cortex and involved in learning, emotion, memory, and motivation.
1/26/2017 20 The Limbic System • Thalamus – Part of the limbic system located in the center of the brain – Relays sensory information from the lower part of the brain to the proper areas of the cortex – Processes some sensory information before sending it to its proper area Figure 2.13 The Limbic System
