This card explains the cortico-striato-thalamo-cortical (CSTC) circuit, a brain pathway strongly linked to Obsessive-Compulsive Disorder. It explores how an overactive “brain loop” may contribute to intrusive thoughts, compulsions, anxiety, and repetitive behaviours.
Using a simple and accessible explanation, the card breaks down how different brain regions — including the cortex, striatum, and thalamus — interact to filter thoughts and regulate behaviour. In OCD, this filtering system may become dysregulated, causing the brain to repeatedly signal that something is wrong or incomplete.
Ideal for students, therapists, mental health professionals, and individuals wanting to better understand OCD, this card combines neuroscience with practical understanding to make complex psychological concepts easier to grasp.
