Deleting the 3 PAR b Zip transcription factor family genes (D site of albumin promoter (albumin D-box) binding protein (DBP), hepatic leukemia factor (HLF) and thyrotrophic embryonic factor (TEF)) accelerates aging and causes severe epilepsy in mice.
The triple knockout mice had a far shorter lifespan: 50% died within 2 months, and ) (mutated in "staggerer" mice with a shortened clock that is only 23.2 hours long) is a core circadian gene that reguilates transcxiptionof Bmal1, which in turn regulates transciption of cryptochrome, which subsequently inhibits the ability of Bmal-1 to activate cryptochrome's own transcription.
The most obvious variation is in the depth of pigmentation of the skin, but most diseases of neural crest derived tissues show differences between Black and White subjects.

Their neoplastic degeneration leads to (unmyelinated nerve fibers found as postganglionic (efferent) fibers of the autonomic nervous system, and as afferent fibers at posterior roots, receiving impulses from free nerve endings that act as thermoreceptors, nociceptors, and interoceptors) are critical in cortical lamination, but very little is known about their origin and development.
The homeodomain transcription factor Dbx1 is expressed in restricted progenitor domains of the developing pallium: the ventral pallium (VP) and the septum.
The fiber bundles pass below the internal capsule, a principal bundle being the inferior peduncle of the thalamus.
The hypothalamic nuclei constitute that part of the corticodiencephalic mechanism that activates, controls and integrates the peripheral autonomic mechanisms, endocrine activity, and many somatic functions, e.g., a general regulation of water balance, body temperature, sleep, and food intake, and the development of secondary sex characteristics.
If this hypothesis is correct, then complete destruction of pre Böt C NK1R neurons should severely perturb and perhaps even fatally arrest breathing.
Specific and near complete bilateral (but not unilateral) destruction of pre Böt C NK1R neurons results in both an ataxic breathing pattern with markedly altered blood gases and p H, and pathological responses to challenges such as hyperoxia, hypoxia and anesthesia.Here we report that in a dynamically changing environment, in which familiar landmarks on the behavioural track and along the wall are rotated relative to each other, the population representation of the environment is more coherent between the original and cue-altered environments in CA3 than in CA1.These results demonstrate a functional heterogeneity between the place cells of CA3 and CA1 at the level of neural population representations : a complex grouping of fibers connecting the amygdaloid nucleus, the piriform area, and the anterior part of the hypothalamus, and various thalamic nuclei.Associative long-term potentiation (LTP) can be induced more easily in young neurons than in mature neurons under identical conditions.Thus, newly generated neurons express unique mechanisms to facilitate synaptic plasticity, which may be important for the formation of new memories are not extensively interconnected.Although these differences have inspired numerous theoretical models of differential processing capacities of these two regions, there have been few reports of robust differences in the firing properties of CA1 and CA3 neurons in behaving animals.
