What is the mouse brain atlas?
The Allen Mouse Brain Atlas is a comprehensive genome-wide map of the adult mouse brain that reveals where each gene is expressed. The mouse brain atlas was the original project of the Allen Brain Atlas and was finished in 2006. The purpose of the atlas is to aid in the development of neuroscience research.
How big is a mouse brain?
Since 2006, there has been a concerted, international effort to create a three-dimensional atlas of the mouse brain, which is roughly the size of a pea and comprised of approximately eight to 14 million neurons and glial cells.
What is the hippocampus?
Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.
What do the brains of mice and the brains of humans have in common?
Human brains and mice brains do have roughly the same number of cell types in the cortex, the outer layer of the brain that handles many sophisticated jobs like planning, decision making and even consciousness, neuroscientist Rebecca Hodge at the Allen Institute for Brain Science in Seattle and colleagues found.
How big is a mouse hippocampus?
The hippocampus is a key forebrain region involved in declarative memory, cognition, and spatial navigation. Hippocampal volume is highly variable with unilateral values ranging from ~2500 to 5000 mm3 among healthy young humans (mean 3,917 mm3, s.d. = 441 mm3) and from 15.2 to 23.0 mm3 among young adult mice [1, 2].
How many neurons are in a mouse hippocampus?
In the hippocampus, the intra-region estimates for the same region had an average standard deviation of 96,000 neurons/mm3, while the inter-region standard deviation was 150,000 neurons/mm3. So regional estimates are still relatively useful.
Why is the hippocampus called that?
hippocampus, region of the brain that is associated primarily with memory. The name hippocampus is derived from the Greek hippokampus (hippos, meaning “horse,” and kampos, meaning “sea monster”), since the structure’s shape resembles that of a sea horse.
What structures is the hippocampus near?
Structure and Function The hippocampus is closely associated with the amygdala, hypothalamus, septum, and mammillary bodies such that any stimulation of the nearby parts also marginally stimulates the hippocampus.
What is the one main ways human and mouse brains differ?
Compared to the cerebral cortex of the mouse, the human cortex is over 1,000 times larger by area and the number of neurons. Although the basic architecture appears to be conserved in mammalian species, previous research has suggested that there are differences in the cellular makeup of the human cortex.
Do mice have a hippocampus?
Since in both man and mouse the hippocampal formation is covered by the cerebral cortex (pallium), it is only its cerebrocortical part, the entorhinal cortex, that is visible on the surface of the brain (◘ Fig. 11.2).
What is the Allen mouse brain atlas?
The Allen Mouse Brain Atlas includes a full-color, high-resolution anatomic reference atlas accompanied by a systematic, hierarchically organized taxonomy of mouse brain structures.
What is the anatomical atlas of the developing human brain?
These anatomical reference atlases illustrate the developing human brain, covering two embryonic stages. The 2D sagittal reference atlas is annotated on Nissl sections collected from an embryo at 15 weeks post-conception (15 pcw). It provides the spatial context for gene expression in the BrainSpan Atlas of the Developing Human Brain.
What is an adult mouse anatomical reference atlas?
Adult Mouse. These anatomical reference atlases illustrate the adult mouse brain in coronal and sagittal planes of section. They are the spatial framework for datasets such as in situ hybridization, cell projection maps, and in vitro cell characterization.
What is the Allen mouse spinal cord taxonomy?
They provide a spatial map for the Allen Mouse Spinal Cord Atlases of gene expression. Dr. Charles Watson and Dr, Gulgun Kayalioglu created a custom taxonomy for annotation of the spinal cord, covering cervical, thoracic, lumbar, sacral, and coccygeal segments.
