Fig. 2. Effects of injection with saline or E. coli LPS on brain and
pituitary tissue CRH levels in tilapia (N=6 in all cases). Open bars
indicate pre-confinement values and solid bars indicate values of fish sampled
following 24 h confinement. The asterisks (*) indicate confinement
effects within a saline- or LPS-treatment group (see Presentation of data
and statistics for details). Upper left panel: sagittal overview of the
brain of tilapia showing the dissected parts (telencephalon, diencephalon,
rhombencephalon and pituitary). The grey areas indicate brain parts that were
discarded: tectum and midbrain, and the rostral part of the spinal cord.
