Otoferlin knock-out mice, which are profoundly deaf due to a failure of sound-evoked neurotransmitter release at the IHC synapse, are likely to be an appropriate animal model for DFNB9. Children harboring biallelic mutations of the OTOF gene displayed profound hearing loss, absence of ABRs and CAP, but preservation of DPOAEs and the amplitude of CM. Patients with variants in OTOF displayed milder hearing loss, as well as progressive and temperature-sensitive hearing loss, while OAEs were preserved. The majority of these mutations are assumed to be nonsense or truncation mutations that provoke the inactivation of otoferlin. To date, about 220 pathogenic variants in OTOF have been identified. Mutations in the gene encoding otoferlin are responsible for autosomal recessive profound prelingual deafness, DFNB9. Otoferlin is also involved in vesicular reformation, re-supply, and tethering at the active zone, making otoferlin a multi-tasking protein. The OTOF gene encodes otoferlin, which is a critical calcium sensor for synaptic exocytosis in cochlear IHCs. These auditory pathologies are named auditory neuropathy spectrum disorder (ANSD), in which the activity of outer hair cells (OHCs) is maintained. The potential sites of damage are diverse, including the IHCs, IHC ribbon synapses, or synaptopathy, (e.g., pre-synaptic release of glutamate or postsynaptic terminals dendrites of the spiral ganglion neurons), or can be due to demyelination and axonal loss of the auditory nerve fibers and their targets in the cochlear nucleus (i.e., neuropathy). A dysfunction at any level of this complex transduction machinery may disturb the coding of acoustic features, particularly of temporal cues. This initiates the generation of neural spikes in spiral ganglion neuron (SGN) fibers, which encodes information about sound stimuli that is sent to the central nervous system. The release of glutamate in the synapse activates Ca 2+-sensitive AMPA receptors. The coupling of Ca 2+ channels at the presynaptic site of the ribbon synapse triggers high-rate synaptic vesicle fusion and the release of neurotransmitter glutamate from the synaptic cleft. This results in a depolarization potential, allowing an influx of calcium through voltage-dependent calcium channels. The hair-bundle deflection induces rapid opening of sensory transduction channels, leading to the generation of an influx of cations into the IHC. That about sums it up and now you're good to go on some of the betterlooking maps.Hearing in mammals relies on the ability of the sensory hair cells to convert sound-evoked mechanical stimuli into electrochemical signals. Sell in massive bulk to prevent price decrease. ![]() Sell your harvest, dont wait for great demand, it is not that good in this game. ![]() They produce wool over time which you can sell for a small fortune depending on difficulty. Sheep are the best starting animal, all they need is water and grass/hay. Fertilizer comes in solid and liquid form, they count as the same. Seed and fertilizer from pallets is cheaper than from automatic dispensers. Harvesters, all headers fit on all harvesters, though low end harvesters might have issues moving with the biggest headers. ![]() It is much faster than picking bales up with a spike and placing them manually onto a flatbed. Buy a flatbed to transport pallets with, but buy an autoloader to pick up and transport bales. Things have HP requirements, on flat maps, you can get away with a little underpowered tractor, if your field has a hill on it, you can't. Or loading wagon to pick up straw and hay and dump it somewhere in your yard for animal use. Plough to plow fields, cultivator to cultivate them, sower to seed them, harvester to harvest them, baler to bale straw, mower to mow grass, baler to bale hay, wrapper to wrap hay and make it into silage. Sure, you can learn the basics there, but its farming. Unless you don't mind the complete absence of any realism. I'd say sod Goldcrest Valley and start on a mod map.
