Do rats with retrosplenial cortex lesions lack direction? by Pothuizen, Helen H. J., Aggleton, John P., Vann, Seralynne D.

“…The retrosplenial cortex is seen as a convergence point for different classes of spatial cue, yet aside from allocentric processing, little is known about…”

Dissociation of function between the dorsal and the ventral hippocampus in spatial learning abilities of the rat: a within-subject, within-task comparison of reference and working spatial memory by Pothuizen, Helen H. J., Zhang, Wei-Ning, Jongen-Rêlo, Ana L., Feldon, Joram, Yee, Benjamin K.

“…Lesions restricted to the dorsal, but not the ventral, hippocampus severely impair the formation of spatial memory. This dissociation was first demonstrated…”

Ethological concepts enhance the translational value of animal models by Peters, Suzanne M., Pothuizen, Helen H.J., Spruijt, Berry M.

“…The translational value of animal models is an issue of ongoing discussion. We argue that ‘Refinement’ of animal experiments is needed and this can be achieved…”
