Parahippocampal gyrus
The parahippocampal gyrus runs along the hippocampus in the lower, inner temporal lobe. Its anterior part is covered by the entorhinal cortex. It is connected to numerous areas of the cerebral cortex and projects to the hippocampus, which it also acts as a gateway to. This means that it is involved in the consolidation of explicit memory content, among other things. In addition, the posterior part of the parahippocampal gyrus contains the parahippocampal place area (PPA), which responds particularly to complex visual scenes such as rooms, landscapes, or streets and thus plays an important role in spatial orientation and location recognition.

Parahippocampal cortex
The parahippocampal cortex is located next to the hippocampus and is part of the temporal lobe. It processes spatial-visual memory content and appears to be involved in the consolidation of memory content. It receives inputs from numerous polymodal cortical areas, and its outputs go to the hippocampus, amygdala, and striatum.

Fusiform gyrus
The fusiform gyrus is located in the inferior, i.e., inner temporal lobe and plays an important role in object recognition. Facial recognition is believed to take place in the right fusiform gyrus, which is why this structure is also referred to as the fusiform face area.

Ventral pathway
The part of the visual processing pathway that deals with size, shape, color, and ultimately object recognition. The what pathway runs from V1 and V2 to the areas of the temporal lobe.

Angular gyrus
The angular gyrus is part of the cerebrum and is considered part of the parietal lobe. Anatomically, however, it is located at the intersection of the temporal, occipital, and parietal lobes. Functionally, visual and auditory impressions are integrated here, and it is also involved in writing, reading, and arithmetic.

Jennifer Aniston neuron
The neuroscientific granddaughter of the grandmother neuron: In 2005, Rodrigo Quian Quiroga and his team discovered nerve cells in the temporal lobe of epilepsy patients that reacted specifically to certain objects – such as a picture of actress Jennifer Aniston. The angle from which the photos were taken was irrelevant. These neurons are part of a network of neurons that together represent a concept. However, there are strong indications that these cells are responsible not only for a single concept, but for several.

Auditory cortex
The auditory cortex is a part of the temporal lobe that is involved in processing acoustic signals. It is divided into the primary and secondary auditory cortex.

Lateral nucleus
The lateral nucleus belongs to the basolateral nucleus group of the amygdala. The basolateral amygdala is the largest part of the amygdala. It receives sensory information from the temporal lobe and neuromodulatory signals from the VTA, locus coeruleus, and basal forebrain, processes them, and sends them to the central nucleus. It is important for emotional learning and fear conditioning.

The Amygdala
Without the amygdala, humans lose their sense of fear. With the amygdala, they also recognize the fear of others.

Praepiriform area
The praepiriform area is part of the piriform cortex in the ventral temporal lobe and belongs to the primary olfactory cortex, i.e., the primary olfactory cortex. Among other things, it contains inputs from the olfactory bulb (bulbus olfactorius) and is therefore involved in the initial cortical processing of olfactory stimuli.
