Figure 1From: Expression of TRPM8 in the distal cerebrospinal fluid-contacting neurons in the brain mesencephalon of ratsImmunofluorescence of distal CSF-contacting neurons in rat mesencephalon. Neurons labeled with tetraethyl rhodamine isothyocyanate (TRITC, red) after intraventricular administration of CB-HRP, were found in the mesencephalon ventral to the aqueduct. The number of labeled neurons varied in different sections (A, B). AQ: midbrain aqueduct. Scale bar: 100 μm.Back to article page
