Your brain has three main parts. The parts are called the cerebrum, the cerebellum, and the brain stem. The cerebrum makes up the largest part of the brain. The cerebellum is underneath the back part of the cerebrum. The brain stem connects with the spinal cord at the bottom of the brai...

and brain stem appear to be made from continuous tissue, but in fact, they're also organized with left and right sides. The left and the right sides of the brain do control different body functions, such as movement and sight. The brain's right side controls the motion of the left arm...
In an attempts to describe the early development of the brain stem-spinal projections, we implanted DiI crystals at the C3 level of the spinal cord of 13- and 14-day fixed embryos. After a diffusion period of 2 to 4 months, neurons of the rhombencephalic reticular were retrogradely labeled...
Structure and functions of the brain stem The structure of the brain stem is first explained from a general view (Fig. 36), principal pathways (Figs. 37 and 38), cranial nerve nuclei (Fig. 39), and reticular formation (Fig. 40), then through a series of 16 axial (horizontal) sec.....
Anxiety is known to dysregulate the salience, default mode, and central executive networks of the human brain, yet this phenomenon has not been fully explored across the STEM learning experience, where anxiety can impact negatively academic performance. Here, we evaluated anxiety and large-scale brai...
Scientists can assemble small sections of human brain tissue made from stem cells in a special container.But in such a container, "neurons(神经元) don't grow to the size,to which a human neuron in an actual human brain would grow," said Sergiu Pasca,the study's lead ...
Brainstem regions support vital bodily functions, yet their genetic architectures and involvement in common brain disorders remain understudied. Here, using imaging-genetics data from a discovery sample of 27,034 individuals, we identify 45 brainstem-ass
4. The response of trigeminal brain stem neurons in the awake animal to such stimuli consisted of short (approximately 3 ms)- and long (approximately 25 ms)-latency discharges whose thresholds suggested that they were both due to inputs from fast conducting primary afferent fibers. 5. Light ...
females have significantly higher risk for myocardial infarction at lower systolic blood pressure than males5. Recent genetic studies have also found genetic risks differ by sex for psychiatric and neurologic conditions6,7. Underlying reasons complex traits differ by sex may stem from many factors, in...
