Therefore, damage to the amygdala can cause serious problems, such as poor decision-making and impaired emotional memories. As a result of neuronal loss, the extracellular space is enlarged and thus diffusion of water molecules is greater on the affected side, resulting in increased values on the affected side (higher signal on ADC). The amygdala also communicates with other areas of the brain, including the hypothalamus, which then releases the stress hormone cortisol. Your age is a risk factor and not a cause of BPH. The assembly of the tetramer and the exit from the ER is controlled by a RNA editing step in the GluA2 subunit: the Q/R editing in the pore loop blocks tetrameric assembly and retains the GluA2 protein at the ER whereas the unedited subunits immediately assemble and traffic to their postsynaptic target via the Golgi complex (Fig. The same information can also travel via the cortex, where it is put together to get the whole picture.
