The Hindbrain Structures Under the Cortex 2 7

The Hindbrain

Structures Under the Cortex 2. 7 What controls emotion, learning memory and motivation? • Limbic system – located under the cortex and involved in learning, emotion, memory and motivation

o r t e x The wrinkled outermost covering of the brain WHY is the cortex so wrinkled?

2. 8 What parts of the cortex control the different senses and movement of the body? The Two Hemispheres “The cortex is divided into two sections called the cerebral hemispheres, which are connected by a thick, tough band of neural fibers (axons) called the corpus callosum …. The corpus callosum allows the left and right hemispheres to communicate with each other” – Page 59 (Ciccarelli & White)

Four Lobes of the Brain • Both the left and right hemispheres can be roughly divided into four sections

Association Areas of Cortex 2. 9 What parts of the cortex are responsible for higher forms of thought? • Broca’s Aphasia - condition resulting from damage to Broca’s area (usually in left frontal lobe), causing the affected person to be unable to speak fluently, to mispronounce words, and to speak haltingly. • Wernicke’s Aphasia - condition resulting from damage to Wernicke’s area (usually in left temporal lobe), causing the affected person to be unable to understand or produce meaningful language.

Split Brain Research 2. 10 How does the left side of the brain differ from the right? • Corpus callosum sometimes severed to reduce seizures • left visual field right hemisphere • light visual field left hemisphere

Hemispheres of The Brain

The Endocrine Glands 2. 11 How do hormones interact with the NS and affect behavior? • Endocrine glands – secrete into bloodstream hormones that target specific organs
