The densest projections in R67 terminated in the following areas: (i) Te3, (ii) Te2 and the adjacent ventral portion of the lateral secondary occipital cortex (Oc2L), and (iii) all portions of Te1. Projections to Te2, Te3 and Oc2L avoided layer V and showed a columnar organization: columns exhibiting dense projections alternated with columns exhibiting moderate projections (Figs 2A, 3C). Collator note: strong connections to the auditory areas that are dorsal and ventral from AUDp, respectively. See Fig. 3B, Swanson Atlas Levels 37-39.

General description technique/protocol: Four rats received injections of PHA-L into the core of Tel (R31, R27, R66 and R67; Fig. 1B). Collator note: experiment R67, the injection site is mapped onto AUDp, Swanson Atlas. The injection shown in Fig. 2A is mapped onto Swanson Atlas Levels 36-38 (the position and the extent of MGd and MGv, the CA1-CA3 fields shapes, and the stria terminalis around the auditory thalamic nuclei were taken as landmarks), where the AUDp has the maximal dorso-ventral extent. It is possible that the tracer spilled in the AUDv rostrally and TEv caudally.
