The bilateral CAU and PUT, parts of the dorsal striatum, showed widespread positive correlations with entire cortical areas.
Instead, drug-related cues (e.g., images, situations) produce an anticipatory dopamine release in the dorsal striatum (caudate and putamen) and basolateral amygdala (10).
This review seeks to describe the function of eCBs in behavioral processes and the structures that regulate it, such as the hippocampus, dorsal striatum, ventral striatum, amygdala, and prefrontal cortex (PFC), and the possible clinical implications of this.

The nigrostriatal system, which is strongly related to motor function, originates in the zona compacta of the substantia nigra (SNpc) and sends projections to the dorsal striatum (STR).
For this purpose, we transform our images in 8-bit color grade (i.e., grayscale), and four random fields were chosen in the target area (dorsal striatum).
We counted 9 fields located at the dorsal striatum per section and 3 sections/animal (N = 5 animals per group) for all experimental groups (Figure 1).
In general, the extended amygdala does not seem to directly influence functions in the dorsal striatum. However, because neurotransmitters involved in stress responses and reward behaviors (e.g., corticosterone, dopamine, and serotonin) can influence striatal plasticity, a functional link clearly exists between the extended amygdala and the striatum.
The dorsal striatum, including the caudate and putamen, was sampled from four randomly selected rats immediately after the locomotor activity measurements (except L-THP (10)/METH group).
The authors argued that the dorsal striatum might be critically involved in reducing the bias produced by salient stimuli when various types of information have to be processed and integrated for a response to be selected [57].
A more accurate statement would be that dopamine is released by the substantia nigra pars compacta or the ventral tegmental area and activates five different types of receptors in the dorsal striatum, which is involved in motor control and habit learning, and in the nucleus accumbens, which is implicated in reward processing and in many other brain regions.
Regions of interest (ROI) with fixed sizes were drawn bilaterally over the striatum, ventral striatum and dorsal striatum. The occipital cortex was used as the reference region.
The striatum is usually divided into two areas, the ventral striatum and the dorsal striatum. The dorsal striatum is the sensorimotor-related part of the striatum and it is composed by the putamen-caudate complex.
Interestingly, recent work (Corbit and Janak 2007) has also implicated the dorsal striatum. The sensorimotor striatum in particular appears to play a critical role in the ability of reward-predicting cues to enhance instrumental lever pressing.
