Abstract
From an evolutionary perspective, perception and memory are fundamental capacities of living beings providing adaptive behavior that is necessary for survival in ever-changing environment. Conscious and unconscious perception is generated by the interaction between many brain regions following the transduction of sensory stimuli. Sensory processing leads to cortical integration of the sensory impressions that are eventually converted to memory representations; the efficiency of sensory integration and memory retrieval underlies adaptive behavior. Everyday activities as simple as, for example, drinking water could be differentially perceived depending on an individual’s emotional and arousal state. The contextual, environmental, and emotional importance of the perceived stimuli determines if the subjective experiences are subsequently remembered.
