Step 1: The neocortex is the part of the brain that is responsible for higher-level cognitive functions, such as language, planning, and abstract thought. Show more…

The tectum is a structure in the mid-brain that helps to orient us in our environment. Humans are the only animals who have reward centers located in the brain. Mirror neurons are those neurons that only become activated when we see our own reflection. If a person who is blind consistently and exclusively uses one particular finger to read Braille, the regions of the motor and/or somatosensory cortex dedicated to that finger may increase. Adult humans cannot generate new brain cells. In a developing fetus, the cerebral hemispheres do not begin to form until the third trimester of pregnancy. In general psychologists now agree that genetic and environmental influences interact to produce behavior. Epigenetic marks are chemical modifications to DNA that can turn genes on or off without altering the underlying DNA sequence. Disconnecting the two hemispheres of the brain by cutting the corpus callosum results in paralysis and Broca's aphasia. Hearing people usually use the left hemisphere of the brain to process spoken language. In order to monitor the electrical activity in the brain that is triggered by viewing horror movies, researchers should use an MRI. We ordinarily use only 10 percent of our brains.

The thin layers of neurons covering the mammalian brain, which are most well developed in carnivores, cetaceans, and primates, is termed the __________: a. the cerebellum. b. the thalamus. c. the cerebral cortex. d. the hippocampus. e. the anterior commissure. One explanation offered for the rapid expansion in the size, mass, and volume of the mammalian brain, especially in those of humans, is __________: a. the cessation of apoptosis during embryonic brain development. b. an increased number of mitotic divisions of founder cells in the proliferation phase. c. the rapid division of mature neurons in the cerebellum shortly after birth. d. the expansion of the volume of the ventricles in adult mammals. Vesicles full of neurotransmitter are carried away from the soma and toward the axon terminal through the process of __________, while depleted vesicles and those containing re-absorbed neurotransmitter are carried toward the soma through the process of __________: a. anterograde axoplasmic transport/retrograde axoplasmic transport. b. retrograde axoplasmic transport/anterograde axoplasmic transport. c. facilitative transport/passive transport. d. endocellular cyclosis/exocellular cyclosis. The small protuberances in the cortex of the mammalian brain are termed __________, while the small grooves in between them are termed __________: a. gyri; sulci. b. sulci; gyri. c. projections; tracts. d. hillocks; fissures. The evolution of the __________ began with the mutation of a sea squirt larva, which was maintained in a juvenile form even as it became reproductively viable--a process termed __________: a. solid ventral nerve cord: pleiotropy. b. hollow dorsal nerve cord: neoteny. c. cortex: polygeny. d. hypothalamus: proliferation.
