Ribots law, which states that events just before an ictus are most vulnerable to dissolution, whereas remote memories are most resistant The frontal lobes are involved in the registration, acquisition, or encoding of information; the retrieval of information without contextual and other cues; the recollection of the source of information; and the assessment of the temporal sequence and recency of events. Studies have also shown that the left medial temporal and left frontal lobes are most active when a person is learning words, whereas the right medial temporal and right frontal lobes are most active when learning visual scenes. Dysfunction of the frontal lobes may cause distortions of episodic memory as well as false memories, such as information that is associated with the wrong context Semantic Evidence that this memory system is different from episodic mem ...

[On plastinated brains, the olfactory bulbs often remain attached to the inferior surface of the frontal lobes ]. The optic nerve (II) passes through the optic foramen to the retina of the eye, and provides the sense of vision. [The optic nerve and optic chiasm can also be seen on most plastinated brains]. The three nerves that are motor to extrinsic eye muscles (oculomotor III, trochlear IV, and abducens VI) all pass through the superior orbital fissure. The ophthalmic nerve (V1), is sensory to the eyeball also and also passes through the superior orbital fissure. It then travels across the top of the orbit, emerging on the forehead through the supraorbital foramen (notch). The maxillary nerve (V2), which is sensory to the nose, face, and maxillary teeth, passes through the foramen rotundum, travels through the floor of the orbit, and then emerges on the fa ...

The cerebellum is responsible for maintaining smooth movement and balance. The thalamus lies at the top of the brain stem and serves as the major sensory relay center for the brain. The hypothalamus regulates emotions, body temperature, basic drives, such as, hunger, thirst, sex, and aggression. The hypothalamus influences the pituitary gland, which is considered the master endocrine gland. Additional structures in this area form an interconnected group known as the limbic system, which involves arousal and the regulation of emotion, motivation, and memory. The Cerebral Cortex Above the lower-level brain structures lay the two cerebral hemispheres, called the cerebral cortex. The cerebral cortex, the outside surface of the brain, is divided into four lobes: frontal, parietal, occipital, and temporal. The frontal lobes control voluntary movement and speech. The frontal lobes are also involved with self-awareness, the ...

Most patients with MDD are women. Prior to adolescence, boys and girls are equally likely to experience depression. In adults, about 2/3 of patients with depression are female. Genetic Contributions to Depression Concordance rate between identical twins is about 40%. Adoption studies support a role for genetics in depression. Families with depressed members also have very high rates of anxiety disorders. Environmental Influences on Depression Prenatal events may lead to depression. Environmental stress may trigger an episode of depression. Brain Structure and Function in Depression Happy moods are associated with activity in the left frontal lobes . Depression is correlated with increased right frontal lobe activity and decrease ...

This component is useful for studying language and the brain because it provides a measure of semantic processing, in particular it opens a window onto the time course of contextual integration during sentence comprehension. Broca's aphasics show a decreased N400 for semantically anomalous targets providing evidence that Broca's aphasia is a result of a processing deficit, in particular a deficit in contextual integration. Frontal Lobes 3. What is meant by the phrase "environmental control of behavior"? What are clinical symptoms a frontal patient might experience that fit this description? Describe behavioral and ERP evidence linking frontal lobe damage to environmental control of behavior. Environmental control of behavior (stimulus driven behavior) means that one's behavior is under the control of one's immediate environment rather than being directed by one's goals and or one's sense about what types of behaviors are appropri ...
