A diagram that shows the structure of a histaminic neuron and its effects on the brain. The diagram is divided into two sections one on the left side and one in the right side. The left side of the diagram shows the histamineine neuron which is a type of neurotransmitter that helps to regulate the neurotransmitters in the brain and regulate the activity of the neurotransmitter. The neurotransmitter is represented by a green circle with the letters "HA" and "N" inside it. The green circle represents the signaling pathway of the neuron while the blue circle represents signaling pathways of the receptor. There are also several other neurotransmitter pathways such as "Vigilance" "Attention" "Feeding" "Working Memory" "Cognition" "Sensory Gating" and "Other". These pathways are connected by arrows indicating the direction of the signaling pathways. The arrows are labeled with the names of the receptors and the diagram also includes a label that explains the different types of receptors and how they interact with each other. The background of the image is blue and there is a label at the bottom that reads "Drug Discovery Today".
