The intranuclear length of the electrode trajectory according to the ‘port’ model for deep brain stimulation of the nucleus accumbens

I read the article by Zhang et al. (1), on deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) for the treatment of neuropsychiatric disease, with great interest. They describe the development of a new electrode for simultaneous and independently programmed stimulation of the nucleus accumbens (NAc) and the anterior limb of the internal capsule (ALIC) based on the anatomical features of the VC/VS (1). The purpose of this communication is to comment on some aspects of the anatomy of the NAc as reported by Zhang et al. (1).
