Orbitofrontal cortex - Wikipedia

https://en.wikipedia.org/wiki/Orbitofrontal_cortex
The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making.In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47.. The OFC is functionally related to the ventromedial prefrontal cortex.

The orbitofrontal cortex is the ventral part of the frontal lobe that processes rewards and punishments. It receives inputs from all sensory modalities and has connections to the temporal lobe, cingulate cortex and other regions.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7749795/
The orbitofrontal cortex in primates including humans is the key brain area in emotion, and in the representation of reward value and in non-reward, that is not obtaining an expected reward. Cortical processing before the orbitofrontal cortex is about the identity of stimuli, i.e. 'what' is present, and not about reward value.

The ease with which we do this relies on a region of the brain sitting directly above the eyes known as the orbitofrontal cortex (OFC). Scientists and neurologists first determined that this part of the brain was important for these abilities by studying people who lacked a properly functioning OFC. People with OFC damage often make disastrous

Abstract. One of the most important factors in decision making is estimating the value of available options. Subregions of the prefrontal cortex, including the orbitofrontal cortex (OFC), have been deemed essential for this process. Value computations require a complex integration across numerous dimensions, including, reward magnitude, effort

The human medial orbitofrontal cortex represents many different types of reward, and the lateral orbitofrontal cortex represents non-reward and punishment. Not obtaining an expected reward can lead to sadness, and feeling depressed. The concept is advanced that an important brain region in depression is the orbitofrontal cortex, with depression

The orbitofrontal cortex (OFC) is regarded as one of the core brain areas in a variety of value-based behaviors. Over the past two decades, tremendous knowledge about the OFC function was gained from studying the behaviors of single subjects. As a result, our previous understanding of the OFC's function of encoding decision variables, such as

The orbitofrontal cortex may be conceptualised as receiving the outputs of all the "what" processing systems, including those that specify primary reinforcers including those produced by taste and somatosensory input (Rolls, 1999a, Rolls and Deco, 2002). In this respect, the orbitofrontal cortex is a unique cortical area.

The information which reaches the orbitofrontal cortex for these functions includes information about faces, and damage to the orbitofrontal cortex can impair face (and voice) expression iden-tiļ¬cation. This evidence thus shows that the orbitofrontal cortex is involved in decoding and representing some primary reinforcers

The orbitofrontal cortex also receives information about the sight of objects from the temporal lobe cortical visual areas, and neurons in it learn and reverse the visual stimulus to which they respond when the association of the visual stimulus with a primary reinforcing stimulus (such as taste) is reversed. This is an example of stimulus

The hippocampus and orbitofrontal cortex jointly represent task

Mizrak et al. use fMRI to demonstrate that hippocampus and orbitofrontal cortex generalize across decisions that share the same task sub-structure compared with different task sub-structures. Results show that the hippocampus, in coordination with OFC, supports decision making by extracting structure from past experiences.
