Telencephalon. The olfactory bulb is located at the anterior part of the
telencephalon (Fig.
Then, 21 tissues (
telencephalon, hypothalamus, mesencephalon, cerebellum, myelencephalon, liver, spleen, heart, eye, skin, foregut, gill, white muscle, hindgut, midgut, red muscle, trunk kidney and gonad) were removed immediately and stored in liquid nitrogen.
The most primitive of the vertebrates, fish, have been described as possessing a poor differentiated
telencephalon, and limited learning and memory abilities (1).
Grossly, brain exhibited dark red to brown multifocal rounded areas 2-3cm in diameter on the cut surface of the white matter of the
telencephalon (Figure 1B).
The known connections of the septal region relate to it most directly to the hypothalamus and those parts of the brain stem and
telencephalon that share significant connections with the hypothalamus.
Left to right: coronal sections of
telencephalon midlevel caudate nucleus; diencephalon midlevel thalamus; midbrain; and hindbrain-level medulla and cerebellum.
It incorporates input from two hemispheres, four lobes in each hemisphere (frontal, temporal, parietal, and occipital), and all five layers of the brain (from the uppermost
telencephalon and adjacent diencephalon below it to the middle layers of the mesencephalon to the lower levels of the metencephalon and myelencephalon).
Samples were taken from the brain (
telencephalon, thalamus, pituitary gland, cerebellum, pons, medulla oblongata, mesencephalon), the spinal cord and dorsal root ganglions, and plantar foot skin.
Anatomically, the small teleost brain shares many features with the mammalian brain, containing a cerebellum,
telencephalon, diencephalon, spinal cord, and hypothalamus (Guo 2004; Mueller et al.
This occurs primarily in the
telencephalon or fore brain, and as unthinkingly as when we walk in the park or enter our kitchen.

telencephalon in embryos of diabetic albino Swiss mice," Diabetologia, vol.
ICAM5 (see Figure 1) is an immunoglobulin cell adhesion molecule highly expressed on the dendrites of neurons in the
telencephalon that is known to have roles in immune and neural functions [65, 66].
