Question

Frontal lobe

Answer 1

Are important for movement and high-level cognition

Answer 2

Large region of the cortex lying between the frontal lobe and occipital lobe of each cerebral hemisphere  Receives sensory information from the body and is participate in spatial cognition (räumliche wahrnehmung)

Answer 3

Large region of the cortex covering the back of each cerebral hemispheres  Receives and processes from the eyes, giving rise to the sense of vision

Answer 4

Large region of the brain lies below the frontal and parietal lobe and to the left of the occipital lobe  Auditive information is received and processed in the temporal lobe  Also associated with the sense of smell and aspects of learning and memory

Answer 5

A loose defined, widespread group of of brain nuclei that strength each other to form a network Contains Amygdala, Mammillary body, Hippocampus, Fornix, Septal nuclei, Cingulate gyrus, Olfactory bulb, Pituitary Gland

Answer 6

: A group of nuclei in the medial anterior part of the temporal lobe. (has several subdivisions with diverse functions such as emotional regulation and odor perception)

Answer 7

One pair of nuclei at the base of the brain

Answer 8

A collection of greymatter structures lying a bit above the Amygdala, implicated in the perception of reward in case of learning

Answer 9

involved in the sense of smell

Answer 10

Located ventral to the hypothalamus. Send of hormones

Answer 11

a fiber pathway that connects the amygdala to limbic structures near the base of the brain, especially the hypothalamus, participating in highly motivated behaviours such as sex and threat responses, as well as the integration of hormonal signals

Answer 12

Contains: caudate nucleus (has a long extension or tail), putamen, globus pallidus and the substania nigra (A brainstem structure in humans that strengths the basal ganglia)

Answer 13

The cerebral hemispheres are directly connected by a few tracts spanning the longitudinal fissure, these hemisphere connecting tracts are called cerebral commissure

Answer 14

A C-shaped bundle which crosses the middle and enables communication between the two hemispheres

Answer 15

The brain region that surrounds the third ventricle. The Thalamus is a complex cluster of nuclei that acts as a switchbox, direction almost every information to the appropriate regions of the cortex, and receiving instructions back from the cortex to control with sensory information transmitted

Answer 16

Part of the diencephalon, lying ventral to the thalamus. The Hypothalamus packed with nuclei which are responsible for many vital functions, such as hunger, thirst, temperature regulation, sex. Works as main interface for the hormonal system of the body

Answer 17

features two bumps in each hemisphere with specific roles in sensory processing (lies between pons and thalamus o Superior colliculi: More rostral bump. Have specific roles in visual processing o Inferior colliculi: More caudal bumps are responsible for audio processing

Answer 18

floor control of movement and sensory system o Reticular formation: A distributed network of neurons collectively referred. It stretches from the midbrain down to the medulla, and is implicated in a variety of behaviours, including sleep and arousal, temperature regulation and motor control o Cerebral aqueduct o Periaqueductal gray o Substantia nigra: delivers dopamine o Red nucleus: communicates with motor neurons in the spinal cord, important component of the sensorimotor system

Answer 19

A distributed network of neurons collectively referred. It stretches from the midbrain down to the medulla, and is implicated in a variety of behaviours, including sleep and arousal, temperature regulation and motor control

Answer 20

Part of the brainstem connecting midbrain to medulla, helps to coordinate body functions such as breathing, respiratory circuits, motor control, posture and balance

Answer 21

A structure located at the back of the brain, dorsal to the pons. Involved in the central regulation of movement (that require precise timing) but also participates in certain aspects of cognition, including learning)

Answer 22

The posterior part of the hindbrain continuous with the spinal cord. Automatic control of breathing of lungs, beating of heart, blood pressure and balance

Answer 23

CSF (cerebrospinal fluid) provides a medium for the exchange of materials, including nutrients, between blood vessels and brain tissue. Also used for bump protection

Answer 24

located within their respective hemispheres of the cerebrum. The volume of the lateral ventricles increases with age.

Answer 25

Situated in between the right and left thalamus

Answer 26

It receives CSF from the third ventricle via the cerebral aqueduct. From it, the fluid drains into two places: the central spinal canal and the subarachnoid cisterns

Answer 27

o located in the left hemisphere in the frontal lobe and in involved in muscles of speak →ability to speak o characterized by partial loss of the ability to produce language (spoken, manual, or written), although comprehension generally remains intact. o Producing speech, sounds

Answer 28

o Located in left temporal lobe o If damaged: Wernicke’s Aphasia: individual may speak in long sentences that have no meaning, add unnecessary words, and even create new words o Understanding speech

Answer 29

• Very young: o Neural tube: An embryonic structure with subdivisions that correspond to the future forebrain, midbrain and hindbrain • Few weeks later: o The neural tube begins to show three separate swellings at the head end • 50 days after conception: o Has already developed a clear subdivision. in the front is the telencephalon which will become the cerebral hemispheres. The other part of the forebrain is the diencephalon which will become the regions called thalamus and the hypothalamus o Behind the midbrain the hindbrain further develops into several principle structures: the metencephalon which will become the cerebellum, the pons and the medulla
