Incorrect. The highlighted region is the Olfactory bulb. The olfactory bulb, involved in relaying olfactory information, receives incoming olfactory nerve fibres, which synapse with the dendrites of large neurons, mitral cells, and form rounded areas known as synaptic glomeruli 1. The fibres of the mitral cells form the olfactory tract 1. The olfactory bulb, in addition, receives axons from the contralateral olfactory bulb through the anterior commissure and the olfactory tract 1, 2.  Link here

Correct! The corona radiata is a fan-shaped wide bundle of fibres in continuation with the fibres of the internal capsule 1. The corona radiata is located above the superior border of the lentiform nucleus 2 and contains both descending and ascending fibres. The descending fibres of the corona radiata originate in the cerebral cortex and travel caudally to become densely packed, converging at the basal ganglia to form the internal capsule 1, 2. The fibres become even more densely packed as they continue past the basal ganglia and the thalamus to form the crus cerebri of the mesencephalon. The ascending fibres of the corona radiata mainly originate in the thalamus, travel through the internal capsule and spread out in the corona radiata to different parts of the cerebral cortex 2.

Correct! The hypothalamus is the inferior anterior part of the diencephalon and extends from the region of the optic chiasm to the caudal border of the mammillary bodies 1. It lies below the hypothalamic sulcus on the lateral wall of the third ventricle 1.
