[ PMC free article] [ PubMed] [ Google Scholar] The arrector pili muscle is a tiny muscle connected to each hair follicle and the skin. When it contracts it causes the hair to stand erect, and a "goosebump" forms on the skin. Your friend who told you about menstrual flow is also grossly misinformed. The heaviness or lightness of flow has absolutely nothing to do with the vagina, in any way, at all. Menstrual flow comes from the endometrium inside your uterus (which the vagina is a path too, but is a separate organ, inside your body), and how heavy a person's flow is is about a bunch of things, primarily on your hormones (especially in puberty where estrogens are so high) but even just a person's height (taller people who menstruate more often have heavier flow, for instance) or weight, or if a person is taking aspirin for their cramps can increase flow. It's not about their vagina: that's only the passage menses passes through: it has no influence on flow. So, now you know better and you can also fill her in on the real deal!

Smith, E. ( 1999) The representation of pleasant touch in the brain and its relationship with taste and olfactory areas. Next, we examined the sN400 as identified in Experiment 1. The result was non-significant ( P=0.131). Because the hand of the somatosensory homunculus sits more laterally than the forearm, we also examined a more lateral region composed of C2, C4 and CP4. Here, a statistical analysis was significant (F[2,118]=26.76, P<0.001). A significant linear term indicated that the sN400 was larger for faster velocities (ß=−4.88, SE=0.67, P<0.0001; Figure6B). The quadratic term was non-significant ( P>0.25).Anderson, D.J. ( 2007) Molecular genetic visualization of a rare subset of unmyelinated sensory neurons that may detect gentle touch.

However, many women with the condition prefer to try and reduce or get rid of the appearance of hair on their nipples for cosmetic purposes. The researchers then similarly marked two other types of touch nerve cells and found that each hair type has a different and specific set of nerve endings associated with it. "This makes every hair a unique mechanosensory organ," says Ginty. Moreover, with their new marking tools, they found that each hair type is evenly spaced and patterned throughout the skin.Acharya J.N., Hani A., Cheek J., Thirumala P., Tsuchida T.N. (2016).

Sci. 1225, 72–82 10.1111/j.1749-6632.2011.05990.x After completing an informed consent procedure, the participant was seated and the experimenter prepared her/him for the EEG recording. The participant then placed her/his left forearm onto a comfortable arm rest under the touch stimulator. In Experiment 1, the arm was placed with a supine position, whereas in Experiment 2, it was placed with a prone position. As the prone position was slightly more effortful to maintain for the duration of the experiment, we attached a couple of soft elastic straps to assist the participant. A curtain precluded the participant from seeing the forearm and the touch device. The touch stimulus in this study was low force (∼0.3N) stroking of the left forearm. In Experiment 1, the brush stroked the participant’s dorsal forearm, whereas in Experiment 2, the brush stroked her/his palm. Although most studies in the field have probed linear trajectories, recent evidence suggests oval trajectories are more pleasant ( Shirato etal., 2018) and more representative of actual touch interactions ( Lo etal., 2021). We, therefore, opted for an oval rather than a linear trajectory. The set points for this trajectory were a ∼15cm circumference, a minor radius of ∼1cm and a major radius of ∼3.22cm. Small deviations from these set points were necessary due to variation in skin area curvature across participants. Strokes were delivered at five velocities including 0.5, 1, 3, 10 and 20cm/s for a duration of 2.5s. Because different velocities necessarily covered different distances across the skin, we adopted a number of control measures. Specifically, we adjusted the starting position of strokes such that motion along the oval was balanced across trials for a given velocity within participants. Thus, all velocities completed the full oval at least once across trials (for further details see Supplementary Materials). So how does the brain interpret what each hair follicle experiences? "How this happens is remarkable and we're fairly clueless about it," says Ginty. But he suspects that the organization of the columns is key to how all the various inputs are processed before a message goes to the brain. And while people are not as hairy as mice, Ginty believes that many of the same structures are shared. This study and the new cell-marking tools they developed, he says, open a lot of doors for new research in understanding touch and other senses.
