**1. Introduction**

Interaction between environment and human beings, as well as each living organism, is essential for survival. Indeed, in nature every interaction among different living species is not possible without the integrity of central nervous system (CNS), which generates brain activity such as arousal, attention, learning and memory. Moreover, face perception and recognition of face are fundamental brain processes for human relationship. The ability to hold objects in memory is essential to intelligent behavior, but its neural basis still remains poorly understood.

Many studies running in the last decades in neuroscience researches have contributed to clarify the intricate puzzle about brain recognizes objects [Ungerleider and Haxby, 1994].

Now, questioning is: "How does brain recognize? What is the neural basis of objects recognition?".

Here, we briefly review neuroanatomical substrates and neurophysiological correlates which could explain the neural basis of object recognition; we also describe our contribution in this field of neuroscience reporting own pharmacological data.
