The category "CNS-development" was chosen here because we reasoned that the strong evolutionary/structural conservation of the planarian and higher animal brains implies conservation of many brain developmental pathways.
Scientists have now shown that food, sex and gambling compulsions employ many of the same brain pathways activated by substance abuse.
Consistent with the notion that this transition is both a developmental and physiological transition, we observe additional axon guidance, developmental and physiological pathways as enriched pathways in many brain region data sets.
The observation that focal adhesion and neuroactive ligand-receptor interaction are both enriched pathways in many brain regions, suggests that signaling either through the extracellular matrix or transmembrane receptors is important during pregnancy, parturition, and the postpartum period.
The midbrain dopamine system, comprising the nigrostriatal, mesocortical, and mesolimbic pathways, is involved in many brain functions, such as motor control, cognition, and reward behaviors [ 1].
However, the changes of gene expression profiles, pathways, and regulatory networks are related to many brain regions which have close relationship to human learning and memory.
Players also showed "abnormal hyperactivity or loss in excitability in their brain pathways", the study said.
Many brain areas exhibit extensive recurrent connectivity.
So many Donnas, so many brain tumors.
Like any brain pathway, the OCD circuit (also called the "worry circuit") becomes larger and faster when used repeatedly.
