1. The hippocampus is "connected" by the fornix and the perforant path to two areas of the brain
which are descriptively named. Identify these areas and indicate the derivation of the
nomenclature. Indicate the type of neural structure to which each is assigned (e.g. striate-cortex=
neocortex). What function is the hippocampus involved in? How might these connections
particularly help mediate this function? Briefly outline the direction of the connections. Describe
how the shape of the thalamus (diencephalon) and brainstem reflect the presence of impinging

Solution
6.The two parts are the posterior part of hippocampus and and the presynaptic part of the
perforant path.
The hippocampus is defined as a a small organ.This organ is usually present within the brain's
medial temporal lobe.Moreover it usually forms a very important part of the limbic system.The
main function of this the region is to regulate emotions.It also plays a very important role in the
process of spatial navigation
.The following are the connections involved.The hippocampus is usually a banana-shaped
structure which is present within the temporal lobe and , The main input comes from the part
which is called adjacent entorhinal cortex and on the other hand the the majority of the output is
sent out through the region called as the subiculum.
7.The shape of thalamus and brainstem reflects the presence of impringing cortcial structures
along the antero-posterior axis becase these two usually involves the global cortical effects of
both theta and ripple oscillations.They also include the the anatomical pathways which helps to
link the hippocampus and midline thalamus .This includes the subiculum and entorhinal
cortex,.As a result it results in the functional connectivity between these networks during the
given oscillatory activity.
The difference between sheep and human brain is that a human brain has a rounded shape while
the sheep’s brain is usually elongated.Moreover The olfactory bulb which is present in both is
comparatively larger in the sheep’s brain and it is smaller in the human brain.
